Some of the largest companies in the world that grew faster than any other company ever with revenues in multiple B are still growing at 3-10x and ppl think there's a bubble.

It's truly wild what you can convince a person of with memes and one liners

Or some of us watch and read a lot of news and investment programming on the topic. Considering I'm not on social media, I'm not influenced by soundbite politics.

An argument can easily be made it's a bubble. It has all of the classic signs of one. There are other threads laying this out so we don't need to rehash it here.

When normal people start discussing something such as this particularly in the context of "revolution" and "this is a really big thing", then for the informed you know a bubble has arrived.

How big it gets, when it pops and what it looks like on the other side are the only remaining elements for the AI bubble.

I think it's a bubble because the rate of expense and build out is outpacing adoption. At some point they have to slow down and let users catch up and adopt the tech. We are probably getting close. I think the next wave of models they role out they'll realize that while super powerful people haven't figured out how to leverage that power, so it's just idle until people catch up. Plus they'll want to charge a premium for them but without use cases people won't pay for it

Grok already pretty much shut down their free tool. It became inaccessible to me 2-3 weeks ago because they couldn't support the compute anymore. I don't need it bad enough to pay for it so stopped using it.

I'm now using my wife's paid Chat sub she has for her business so I get the added delight of occasionally polluting her memory profile with my mess. I at least contain my prompts and queries in my own folder for her.

I might be wrong, but I believe we were in disagreement previously regarding the near-term future of AI within the Product org. Sorry, if I'm getting posters mixed up. We were discussing AI code work, and I took the position that Series B Product work was ripe for AI-generated code since there is a lack of tech and data debt. Now that there has been a good 5-6 months, I'm curious what is driving your concern for a bubble since previously you were very bullish? Is it purely the over investment (and investor-customer relationships) or has there been any communication with your Product org that hints at anything hard to monetize?

This entire thread is tragic.

Personally, I can't wait for the data center build out bubble to burst

It's going to be Broomfield, Colorado, 2001 all over again.


I don't think there is a build out bubble because they are limited by the power shortage and backlog of gas turbines for power. They don't have a way to power all of the data centers they want to build. Many announced data centers are being delayed or the plans being abandoned.

There probably is an AI investment bubble though.


Related to this, Elon was discussing this at Davos this year and said at some point this summer we will have chips sitting on shelves because there aren't enough DC's available to use them for all of the planned AI build out. If he's correct, then we are going to hit a wall this year on DC's anyway.

It can easily be argued AI investment is a bubble. The sheer amount of circularity in that space deems it to be so.

I agree with Burdizzo(?) that these things are going to happen in some form or fashion pretty much no matter what so we have to figure out a way to force them to be good neighbors.



I don't recall saying it, but I agree there is a certain amount of inevitability at play here. Also agree we may be seeing a bubble. Global economy demands more data storage and more computing power. Also think there is a lot of overblown hysteria surrounding loss of agricultural lands. We seem to have forgotten about what clever people like Norman Borlaug can do to feed people.

The small farm where I grew up is being surrounded by new residential development. Some of it isn't great either. It was a great place to grow up, but it wasnt a great farm. Once my brother is done farming (he is in his mid-60s with no kids), that land might very well get liquidated. I would love to be nostalgic about it, but my family can use those proceeds to go buy something else. I certainly can't do anything about the encroachment, and know what some of these tech companies are paying I would probably be glad to sell to them if they came knocking.

Not picking on you as we do consider those things, but this thread and this post as an example is why the Chinese train station that is the subject of another thread could never be built in that location and timeframe in these United States.

Again, not being critical of you post, it's just a sweet juxtaposition into the complexities of building things in the US versus China - and maybe who has the better answer (personally, we need to lean back in the direction of China in this area).

Not sure but I agree with you. I have a Split View on this. In the Product / tech dev space it's huge, and as soon as Claude Code came out we went hard into it at our startup. I boot strapped our first operating system with an offshore team using a COTS product to prove the business plan out with investors. We then started hiring more people and AI really hit not too long after. When Claude Code then arrived we jettisoned the first system and built a new one with it and cursor.

I changed my hiring plans because of it meaning I had to hire fewer people going forward than originally planned. My peer (the CTO) adopted the mindset that most other CTO's have adopted - Claude will be our junior level programmers and seniors will have oversight and get things over the finish line. IOW, Claude does 80% and seniors do the final 20%.

I brought up the next logical thought of "if we aren't hiring and training up juniors then we are ultimately going to run out of seniors over time due to attrition, etc.". CTO: "Will worry about that later." Regardless, you are going to have hybrid product/IT people going forward. That line in the sand between the two is going to disappear and already has in many organizations especially smaller, more nimble ones.

I then retired not too long after we moved this direction so I'm not sure where they have ended up.

Regarding bubble talk, it's from the investment view of things and the handful of companies that are in bed with another over it. Classic investment bubble circularity. In particular, Altman has had trouble even monetizing ChatGPT. He focused too much on retail subs in the beginning and less on corporate. He's had to court KSA and foreign entities to get more funding to float him while they figure it out. Last time I checked in on it, they said they wouldn't be profitable until 2030 which is a lifetime considering how fast things are moving.

Ah, I see. Agreed, especially on the circularity. I don't think most people even grasp the scale of these dollar amounts. Nvidia has already said that in the current projections, they will not invest anymore into OpenAI and Anthropic. That could change, but every other hyperscaler and VC sees that and says, well I'm not going to be dumb money if Nvidia isn't going to participate. That's why you keep hearing IPO. I also don't think people understand that long-term data center growth is so divorced from the current gold rush, but it is what it is.

One thing that has not been discussed, at least I haven't seen it, is the exponential growth in software that will occur because of AI. Training and inference is the focus, but the code that will be genned for just about everything under the sun is going to be another factor in the DC expansion. The coding problem has been solved. I now have numerous apps running on my personal domain in Railway that do financial management (I completely replaced Rocket Money) and various other functions for me. It was never worth doing that before AI came along, too much effort. Now it's almost effortless.

I have not. I have the Max package from Claude and have never hit my session or weekly limit, so I don't really care about what is being consumed. I had the Pro package before and it was good until everyone started using Claude after they refused to bow to Trump's demand to allow civilian surveillance, etc... I was forced to upgrade because of that.

I only have two apps that use an LLM API: one for parsing PDFs and HTML pages (I tried using regex but LLMs are far superior for that kind of task), and one for upscaling images. Those calls are fractions of a cent each time.

The remaining apps are pure node.js, PostgreSQL and HTML/Javascript. No LLM is used in those apps.

Some of y'all have your heads in the sand.

I am married to a man that owns thousands of rural acres in West Texas. We also own land in town. If you rural folks want to be angry, be angry at your neighbor who sold their land because they couldn't afford to ranch anymore. Be angry at the county commissioners or state for throwing money at the tech companies for building these data centers. They are a boom economically for these cash poor counties. The tax benefits are going help build infrastructure for these counties, along with schools and roads.

My backyard from my house in West Texas has a beautiful view. I would be sad if a data center came up between my house and my view. But at the end of the day, I understand why it has to be this way. I don't want to stay behind China and be held hostage by China.

China is a good reason, but let's be honest, when it comes to companies wanting to make money, they'll do whatever they can to make it.

If China wasn't in the arena, if we were the only one in the arena, these companies would still be doing what they're doing. Let's not pretend that them doing it has Americans interests being the reason they're doing this.

There's nothing "they're doing it to protect our freedoms" in what they're doing. It's all about how much money they can make. IF what they're doing happens to help in other ways ("freedom, China, whatever"), that's secondary or tertiary to what they're doing this for.

But, yes, the Lobbyists and mouthpiece of these companies will put out in media/commercials that they're doing this for us. Do it without getting a profit and they're doing it for the good of the citizenry. Do it for a buck, yeah, not so much.

Like I said early in thread, advocates for these need to start figuring out their PR post haste. Trump and the industry agrees with me.

https://www.wsj.com/tech/ai/the-american-rebellion-against-ai-is-gaining-steam-94b72529

Quote:

The only thing growing faster than the artificial-intelligence industry may be Americans' negative feelings about itas former Google Chief Executive Eric Schmidt saw on Friday.

Delivering a commencement address at the University of Arizona, Schmidt told students the "technological transformation" wrought by artificial intelligence will be "larger, faster and more consequential than what came before." Like some other graduation speakers mentioning AI, Schmidt was met with a chorus of boos.

Trump recently said data centers "need some PR help."

"There's a disconnect between what we're saying and what is happening out there, and I think that's the issue we have to address," Ernest Popescu, CEO of the company developing the data center in Indianapolis that Gibson had approved, told the crowd.


Quote:

Consumers resent energy-price jumps exacerbated by the spread of data centers. Workers fear widespread job losses. Parents worry about AI undermining education and harming children's mental health. In recent months, the wave of anger has brought protests, swayed election results and spurred isolated acts of violence.

Hadn't seen this before but Democrats less enthusiastic about DC's than Republicans:

Quote:

The poll showed about 30% of Democrats think America should accelerate AI innovation as quickly as possible, compared with roughly half of Republicans and 77% of tech founders.

Outcomes from all of these protests against AI:

Quote:

Local opposition blocked or delayed at least 48 projects valued at some $156 billion last year, according to Data Center Watch, an organization tracking the trend. A record of 20 were canceled in the first quarter of the year because of local backlash, figures from climate-media outlet and data provider Heatmap show. Dozens more are currently facing similar obstacles on top of obstructions because of permitting snafus and equipment shortages.

On Monday, Texas Agriculture Commissioner Sid Miller called for a moratorium on new hyperscale data-center development in the state, citing concerns about the costs to farmers and strain on the power grid.

Separately, for all the folks on this thread who continue to say that recent DC buildout is simply business as usual...you are lying or are wrong. It's to support AI.

Quote:

The artificial intelligence gold rush is rapidly drying up the supply of the one resource that AI developers can't do without: computing power.

The sharp capacity crunch has caused consternation among power users, forced companies to scuttle products and led to reliability problems. The issues are a warning sign for the AI boom, as they may limit the utility of powerful new AI tools just as massive amounts of users have begun to rely on them to boost productivity.

Companies have been scrambling to secure the availability of computing capacity needed to serve a growing base of customers who are also significantly increasing their AI use.

Quote:

OpenAI scrapped its Sora video-generation app in part to free up computing resources to power coding and enterprise products that would work on a new AI model, code-named Spud, The Wall Street Journal reported.

Token use in OpenAI's APIa platform where mostly enterprise users access its softwarerose from six billion a minute in October to 15 billion a minute in late March.

"I do spend a lot of time trying to find any last-minute compute available," Sarah Friar, OpenAI's chief financial officer, said in a recent public video interview with an investor. "We're making some very tough trades at the moment on things we're not pursuing because we don't have enough compute."

Quote:

Spot-market prices to access Nvidia's GPUs, or graphics processing units, in data-center clouds have risen sharply in recent months across the company's entire product line, according to Ornn, a New York-based data provider that publishes market data and structures financial products around GPU pricing.

Renting one of Nvidia's most-advanced Blackwell generation of chips for one hour costs $4.08, up 48% from the $2.75 it cost two months ago, according to the Ornn Compute Price Index.

"There's a massive capacity crunch that's unlike anything I've seen in the more than five years I've been running this business," said J.J. Kardwell, chief executive of Vultr, a cloud infrastructure company. "The question is, why don't we just deploy more gear? The lead times are too long. Data center build times are long, the power that's available through 2026 is already all spoken for."

That's why, unless you are paying, AI chat is worthless now. You get a couple of prompts and it's locked until the next day (I'm exaggerating a bit but it has gotten real bad).

GROK was at the point where every attempt for about a week failed. It told me it was under heavy usage and to upgrade to SuperGROK. GROK inside X is prioritized and still functions most of the time.

Build so China doesn't beat us. Okay, sure. They'll take themselves down much faster than they take us down with an LLM. Artificial intelligence is a misnomer. It's artificial inference. Tokens are literally syllables. Literally syllables. Where the intense compute and well-trained models allow for incredible syllable matching. That's what historical hallucinations were. It wasn't providing a wrong answer. It was pulling the wrong syllables. LLMs are a paradigm shifter, but there is a reason why Anthropic didn't want their syllable models responsible for life and death decisions. Even if it made the right call, no one could understand why it pulled those sources for that response, when it might have pulled others a few seconds later.

In your software exponential growth scenario, do you think that end users will be cooking up (and maintaining) their own code base like you have?

Or do you think that there will be gazillions of apps available?
We basically already have that now in our phones with Apple and Google.

My guess is that for commercial apps, consumers will still be willing to pay for some expectation of patches, updates and security.

And I suspect that other than small scale enthusiasts / hobbyists, we'll still see consolidation in software apps as people flock to the ones that are "better" in whatever way they're looking for.

If we look at social media as an example, there are beaucoup YouTube, Instagram, X accounts but, only a few have millions of views. If everybody is out there AI coding their own software, I think it will be similar. There might be a million versions of TurboTax (for example) but there will still only be a handful of tax programs that everybody uses.

Anyone paying 1% right now is getting robbed. No need to pay that.

But agree that AI is going to disrupt this space primarily in the lower to mid wealth tiers. ChatGPT just released their own personal financial management software this week as part of their Pro plan. Notably, they mention they are partnering with Intuit so not sure what that means for Simplify or any other Intuit products.

Data centers are going to be such an issue for electricity grids


Most maga-size data centers are installing their own generation and not even connecting to any grid. But many mid-size ones are, so point is partially valid. Also, with the new high-powered severs being liquid cooled, they will just use a heat exchanger to a cooling tower. So, no refrigerated chiller and fin-fan coolers. The cooling towers will use much less electricity (for the cooling, not the chip power), so it's by far the cheaper way to go. But evaporative cooling does consume water, so in dry place like west Texas where cheap fuel gas exists wil, indeed, need to manage the water consumption.


Most are going to a closed loop system with little water use.


No, they are not. Closed loop chilling for the building envelope, but future servers will have liquid immersion for cooling with plate and frame heat exchangers directly to an evaporative cooling tower. They are in the prototype stage now, but will be the future of compute.


Liquid immersion has been the 'future' for at least a decade and is way past the prototype stage, this has not and will likely not be widespread adopted anytime soon.

ETA that if a user went liquid immersion there is absolutely no water needed, it would use a specialized fluid.

This is being used now. I would have liked to see the reaction of the data guys when they were told, "We have an idea. We are going to submerge your servers to cool them".


So what are the current standards for data centers and are all new DC's being built for AI following them? Closed loop vs open loop? Immersion?

Data centers are not all being built for AI. Microsoft, Amazon, etc. are still the big owners. Immersion is still new. But closed loop is how things have gone. There is a reduction in evaporative cooling.

The Stargate data center in Abilene, Texas, is an ongoing gigawatt-scale AI infrastructure project led by OpenAI, Oracle, and Lancium.

Not all of them, but most of them are, and all it takes is most of them.

China has to steal because they can't build. If you can't build, you are too busy stealing while we build. I'm much more worried about China's ability in robotics. And again, not saying we don't need data centers, but the current plan of having PE fund random operators that negotiate with random counties and munis is not the solution or a way to beating China in anything.

but require more electricity.

Please explain.

Close loop systems require more pumping power to move more water and more fan power to cool the hot side water in a chilled water system. If you talking air cooled chillers (which can be considered closed loop as there is no tower at all) they are less efficient overall than open loop systems.

There's a reason open loop systems (water cooled chillers and forced draft cooling towers) have been so prevalent in large cooling systems for a very long time. They cost less money to operate year over year than closed loop systems and they last longer. Especially in area's where electricity is expensive.

Water cooled chillers also have a lifespan of ~25 years. Air cooled chillers have a lifespan of ~15 years (from the last ASHREA data I recall).

And yes, several systems out there to recover 10%-30% of evaporated water, which is only a very small portion of the water utilized in the cooling towers.

Keep your mind open, you will learn more.

How do you recover evaporated water?

Most refer to it as condensation.

I take from this you have no idea what you are talking about. Condensation is from the cooling coils. Evaporative cooling is from cooling towers, and is not recovered.


I take it you have never had distilled water, spirits, beer, etc. Have you ever seen it rain and are you familiar with the water cycle?

Evaporative cooling towers work the same as all other methods of heating and cooling and its driven by heat exchange. Most of the heat exchange is from evaporation but only about 1% of water is evaporated per pass and the vapor plume can be equipped to condense that vapor back to recovered water via various methods.

My degrees are in accounting and information systems. But they are decidedly irrelevant to a basic understanding of the physical states of H2O.

You have no idea what you are talking about. This is not beer. ME '88. No, not 1 percent is evaporated. Reference my high rise example of 80 gallons a minute needed for make up.

You have no idea how cooling towers work. I do not disparage my fellow Ags but you need to sit this one out.



Tell us how they work and cite your sources. Maybe get the slide rule out and show us the calcs.

I notice you dropped your ice battery misinformation after that was cited. I don't think I need to clutter the thread up about cooling towers and how evaporative cooling works, but to think all water is flash steamed in evaporative cooling and lost permanently to the atmosphere never to become water again is frankly bizarre, but who knows what they taught in ME back in the mid 80s.

Fact remains only ~1% of water is evaporated during each pass and 10%-30% of that can be recovered. Rather than trying to shout down at someone who may have been familiar but who went back to check the facts, and looked into any new developments (I was not aware that they have figured out an approach to "ice battery" backups and is in use and not some failed technology from 30 years ago.

Enjoy some reading and again an open mind is needed to learn. Spouting an engineering degree from 40 years ago is not open minded.


Nothing in that article is "new" technology. Some of it can reduce water losses, but it's not as much as you think it is.

The Marley "fluid cooler" in that article is limited in size and how much it cooling it can provide. It's also been around since the before '80's you seem to want to reference. They also use more electricity than the open loop tower they want to turn off when using the fluid cooler.

The plume abated tower also uses less water, but guess what, needs more power to operate and requires a larger tower cell (so more footprint and more fan power) to get the same cooling capacity as a standard tower. I just designed two large cooling plant systems using those exact Clear Sky towers.

EDIT:removing rude comments. But reading a few articles and pretending you know something you've never studied or designed (and I have) doesn't make you suddenly an expert.

Data Centers, okay but don't give these corps any freebies. That is all I care about. If they ruin the environment, jail the C levels and fine them BIG.

This has been my issue with closed loop terminology in my locale. They keep saying it as if it's a standardized system.

Never claimed to be an expert. I was asking questions and not advocating for one system or another. But appreciate your comments, particular the parts about mischaracterizing my posts.
