The problem with this AI stuff is we don't know how much we will be willing to pay for it, as individuals, as businesses, as nations. I guess we just don't know how far this stuff will be useful. The reasons for the high valuation is, in my guess, that there is more value here than what we have tapped so far, right?
The revenues that nVidia has reported is based on what we hope we will achieve in the future so I guess the whole thing is speculation?
