People have been singing that tune for a long time now. Hasn't happened, isn't happening.
I know there's some very good-sounding arguments about how because of high AI demand, there's shortages there, and that every Geforce-destined wafer that gets made is one less H100-destined wafer that can be made, but according to information, their shortage and bottleneck is not coming from lack of wafers, but packaging.
So cutting production of Lovelace parts is not going to help increase the supply of H100's.
The AI chip market is also likely to grow more competitive in the very near future, and there's reasons to think that the explosion in demand will not sustain like it has so far. It could potentially be a huge disaster for Nvidia to put all their eggs in the AI basket.
