It’s a shame there’s inherent performance cost to homomorphic encryption. If there were not it could make sense at least on the compute front to treat it as a commodity and just put it everywhere l, importantly including untrusted locations and have a control plane handle coordination for low latency.

Otherwise why not wipe out these gigawatt dcs? They don’t employ many and are of high consequence for rich countries.

I think it's more the performance cost of building the servers themselves, and their density, why put compute in a flood basin or tornado hotspot if you know the latency improvements won't be immense enough to offset the cost of their destruction

Even biology doesn't cross check that much. Cells are happy to copy virus materials.
