Unfortunately Ed's explanation and understanding of this seems to be a bit naive and not based in the reality of what the market is actually doing. That's not to say that there won't be a correction, but I would not say that "AI is a bubble".
First, nearly all demand for the parts that primarily drive these hyperscaler's systems are accounted for in 2027 so at the very least, this won't even be a thing until 2028 at the soonest.
Second, while tokens are expensive to use today from Anthropic and OpenAI, they will be forced to lower their rates as newer and more affordable options like Moonshot Kimi k3 take the stage at a fraction of the price, making AI access more affordable for corporations and even individuals that can use these models but just don't want to break the bank. Not only are these models more affordable, but they're also built with fewer high cost parts lowering the strain on the market as a whole. And sure, there's a chance that there is an import/export ban on these more affordable Chinese models, but even still, developers will find ways to imitate the cheaper models they created and ultimately mimic them in the US. This in turn will help ease the strain for all companies over the next couple years as Anthropic and OpenAI are forced to actually compete by offering more affordable token costs as individuals migrate to options such as Kimi.
Lastly, like it or not, I don't see AI going anywhere. There are trillions of practical applications for it in everyday life, many of them uses that we don't even realize yet and will subsequently generate many future jobs/opportunities for individuals as people realize how it can be used for problem solving new and unique issues. Sure, AI in it's current state is unsustainable with the lack of profit and massive cost of investment/high cost of entry, but that's the cool thing about the world. People innovate, find cheaper ways to do things, and then force the competition to do the same or leave the market.
So in my opinion, it is not so much as a bubble as it is a process (like anything) where more refinements will be made as ineffeciences are rooted out and improved upon.
