I agree there's some smoke holding up the AI companies; but it's not industry scale smoke.
There's a significant difference between a industry scale bubble busting and AI which is breaking out right now which could theoretically become a bubble but it's far from it. Obviously its possible later next year we see the bubble burst but I expect something rather extreme would need to expand to get there today.
When I look at this index for example, https://finance.yahoo.com/quote/AIQ/
They had a steady decline for all of 2022. Then a big climb, but I estimate they probably have a 25-30% drop coming soon. Just looking at the holdings, they dont scream AI exactly.
Nvidia/cuda obviously being a huge part of AI and they have a pe ratio of 70? There's certainly an nvidia bubble there unless they show some serious profits soon to avoid crash. Though if they do, we'll be kicking ourselves for not buying now.
Moreover, what's important to note. Just because there's some serious smoke going on there, that bears no witness on the future. If these startups showing up can bring a game breaking product to market, then valuations today are imaginary. You want to get in on them now or asap.
I'm not a gambler investor so I never touch anything like this; but I also don't see any dotcom scale bubble that's going to pop.
