Is Nvidia stock overvalued? It depends on the future of AI.

So, then yes it is overvalued.

Yes, yes it is.

Lol, is a lottery ticket overvalued. Not if it wins, but definitely if it loses.

"AI", if it ever does get invented, will be world changing (note the deliberately value-neutral term).

The value of NVIDIA depends on AI being increasingly costly to compute.

This, in particular, is not a foregone conclusion.
