@ephemeral I love thinking through how things could be different!
I do appreciate solid-state drives, & I can see the value in fully-programable GPUs... Or widespread fiber... I don't think I appreciate much else in computing since mid-2000s...
Cryptography improved, & we have CRDTs & DGGS now. But that's software!
Going back to 1980s meanwhile, I think (if your software supported that hardware) most people would probably complain about the limited memory before the limited CPU!
