We already are. Check eBay at the component level, which is showing it quite clearly. Look for secondary/reclaimed/refurbished components to backfill the gaps too.

Also be aware that this stuff whipsaws, if OpenAI actually takes posession of that memory and decides they can't use it and dumps, we're going to see a crash. Likewise if they back out of the deals with the memory fabs (or fail and default). There's some scary volatility on the horizon.
