The link you provide above stalls, so IDK what that is about.
I don't agree that AI is just a marketing term, although it probably is used in that way by many, it is not when it comes to Nvidia, who has the by far most popular hardware to drive AI software. And Nvidia is already making a lot of money on selling hardware for AI, and even lower tier suppliers claim the demand is crazy for AI hardware.

VCs will get sick of setting money

Do you mean venture capitalists? It's very annoying to have to guess the meaning of a 2 letter acronym. For Christ sake how many meaning do you think VC has?
What special contact do industry peons have with venture capitalists? That doesn't make any sense. Also I don't believe this is driven by venture capitalists at all.

All the biggest companies like Microsoft, Google, Facebook etc are making huge investments in their own implementations, implementations that cannot even be finished this year because of supply shortages. This is not about upstarts, but all the biggest existing companies investing huge amounts of money. Upstarts funded by Venture capitalists are not even a blip on the radar.

So saying 3 quarters is absolute bullocks, that doesn't even cover NVIDIA's back orders!

this is a bubble fueled entirely by investors,

Nope, there is actual crazy demand. But how crazy in the longer run remains to be seen.
