The trillon dollars question is more, will the current GPUs still be relevant in 3 years? 5? 10?

Will incredibly efficient new GPUs appear? will custom ASIC, models burned in silicons, take off? Will unified memory systems become usable?

The datacenter bets are that things will mostly continue like now, and that these GPUs won’t depreciate too much.

For now theses bets are self-fulfilling, causing hardware to even appreciate.
