It is always about scale. At scale today's Nvidia does anything is so big that 100x is not anymore reasonable. Or then it is not significant...

From sub million to hundreds of millions I could theoretically see. Even tens of millions to billions. And even then I would be extremely skeptical.

But with Nvidia we are talking somewhere in the scale at tens or hundreds of billions. And that is actually very large sums of money. Even if it often does not look like it.
