Is Nvidia stock crashing is a sign of the AI bubble about to burst?

I've been thinking all this money thrown at """AI""" companies that are nothing more than running ChatGPT in the background is similar to what happened in the dotcom bubble. A company could just say "oh yeah we're leveraging breakthrough HTML technology. We're disrupting the brick and mortar stores because we're a dotcom!"

ChatGPT isn't even profitable, and so isn't many of these other AI models. They're just surviving off of investor funds. I think a lot of investors will be in for a rude awaking when they realize their investment in an AI toilet seat company doesn't make returns.

I think Nvidia is super super overvalued. It didn't shoot up in value until the AI buzz happened. Really at their core, they are a company selling graphics cards to gamers. It just so happens AI runs really well on their graphics cards.

Maybe investors are realizing that companies touting AI can really only talk the talk and not walk walk. As I type this, Nvidia stock is lower than it was 6 months ago.
