Most of humanity hasn't figured out they need to adapt yet. It's a bit like email and the internet in the mid nineties. People had heard about it but hadn't really embraced it yet. Five years later most people with white collar jobs had email addresses. Fifteen years later, billions of internet capable smartphones were in circulation.
The AI revolution is following a similar adoption curve. Right now many of the tools are only really usable if you are a developer or at least not too shy making AI agents use developer tools on your behalf. That's not going to stay like that for very long. It's going to be a messy transition that will likely take much longer than some people seem to think. But eventually most people doing knowledge work will be leaning heavily on all sorts of AI agents to do their thing. And quite a few will have to learn new skills as most of the stuff they still do manually today just goes away as a thing that you do manually.
Like the mid nineties, these are amazing times for people with a slight head start over everybody else. Which is why there is such an investment frenzy around AI right now. Lots of possibilities where lots of money might be made. And lots of things that won't work out. And lots of people really not seeing the forest for the trees as well. And generally behaving like headless chickens. But the internet in the end proved to be not a fad and it didn't all go back to normal after the hype died and the .com bubble burst.
IMHO, the bubble around AI is not so much the technology but things like data center and energy pricing. The cost of data center production is long term a fraction of current cost (dominated by GPUs costing tens of thousands of dollars). Likewise cheap and plentiful energy to power them is going to eventually cost a lot less. Short term scarcity eats up a lot of billions right now. But you'd be mistaken to confuse that for long term structural cost. Cost is going to come down and that will drive adoption. And that's before you consider edge compute on commodity phones and laptops. There will be billions of devices running small AI agents. Add robotics to the mix and it's a whole new world.
In short, companies like OpenAI and Anthropic are valued so high because all of that is happening right now. Yes, it's a bit of a bubble. But stuff will definitely happen.
