Yes that was the joke

The only ones guaranteed to make money in a Gold Rush are the ones selling shovels.

That said, NVIDIA made the mistake of lending money and/or investing directly in the ones doing the "gold mining", so now they're heavilly exposed to the side of things that loses a lot of money when it turns out that it was all Fools' Gold.

When it comes to manias, some things are always the same.

Jensen seems to be concerned though about the bubble bursting. he probabl wont see immediate effect, but since he switched to mostly AI chip production/design, he will likely lose alot once it hits.

They kinda do, with their own models for upscaling and stuff integrated into videocard drivers, and it's not cheap or easy, but it's peanuts compared to what AI companies spend.
