My first comment was tongue-in-cheek to slightly mock overzealous bulls. Is the market in a bubble? Maybe...
Smart money employs capital where there is value. There are good reasons to be heavy in the Mag 7. Obviously, that is where most see value. What value? Artificial intelligence. Why AI? Bottom line...AI has great potential to create efficiencies. Efficiency is an elemental backbone to increase production and reduce costs.
Think of some of the most prolific machines and inventions of the industrialization age: the tractor, the automobile, the cotton gin. All added to efficiencies: greater production, reduced costs, growth, opportunity, increased employment, improved quality of life, and great wealth.
As a technology, AI is still learning to walk, but there seems to be infinite possibilities where this technology could be deployed to create immense efficiencies and reduce costs. I've even entertained the idea of using AI to replace government, a wholly inefficient and wasteful institution. Naturally, we need to keep some guardrails on AI to insure it remains a public positive and not a societal detriment.
Banking, finance, and markets are smack in the middle of an evolutionary change. Crypto currencies, blockchain, stablecoins, smart contracts, tokenization of assets, etc... AI will play a huge role in this sector as well. Currently, money flows like a river; bending around trees, banks, and rocks. With AI, money will flow at the speed of light.
I think most of the doom comes from those clinging to old ways and not terribly comfortable with change. I fully admit I am one of those people. I see the potential of AI as I work in the technology sector and use it daily. And that's probably what scares me the most; watching these infant technologies reshape the world.
In 1983, just a kid, I stood in a Radio Shack looking at a "personal computer" as my dad was shopping for something. The salesman came over to me, smiled, and said, "You can learn to work on one, or push a broom around one." I think that's kind of where we are with some of these new technologies.
