From which generation are we counting from and until what generation are we counting to?
The entire industry got borked by crypto and covid during the 3k series.
The 4k series got borked from being designed and priced based on expectations that crypto would go on.
The 5k series will likely get borked by its goals likely set on many of the same assumptions that borked the 4k series and could be too far along development to correct.
The 6k series should be the one where Nvidia will be forced to admit its unrealistic expectations have crashed and burned, though it may still try its hands at inflated prices for the performance it delivers one more time, albeit not as brazenly.
So the 7k series is where I would expect Nvidia to have mostly cleansed itself of covid-crypto greedflation and return to more normal greed.
If we count inclusively from the moment greedflation set in to the moment it is mostly gone, that would be five generations (3k through 7k) for me.
