Alex is a smart guy. Listen to Alex.  "Pure clients need to exist for freedom reasons" but we can have the server model (client proxies) whenever that trust/speed tradeoff is needed.

 I had a dream last night of a server farm of GPU accelerated nostr relays. I have no frickin clue what good a GPU would do in a database, but there has to be some kind of index lookup problem that can be solved with GPUs, like reverse-merkle hash trees or whatever. 

 There are gpu accelerated databases like BlazingSQL or Kinetica. GPUs could be used to accelerate signature verification of incoming events. Another application could be graph-based parallel search at the relay using gpus to speed content search operations.
