Yes. All these companies making "investments" in each other, where company A puts 10 billion into company B and company B buys 10 billion of company A's products can't work out well in the end. This is separate from the concept that AI has real value. Pointing out the likely doomed to fail huge mutual investments is a separate issue. We can have two ideas in mind about something.

I am worried about the damage when this ends. Sure, there's way over exuberance in my opinion about the value of all this vast amount of spending and infrastructure (datacenters, billions or trillions more in training hardware from nvidia etc). But there's this other completely bonkers level where it's just normal to give some billions for some stock and they turn around buy billions of your stuff.

This has to run into reality at some point.
