[ExI] Quantum computers in just a few years

[Jason Resch]

Will quantum computers be useful for anything?

- They're too low memory to have any utility in AI training.

- By the time they're large enough to crack RSA or ECC keys, we will have
moved to Post-Quantum-Secure cryptography.

The only claimed benefit I have seen that seems to hold any water is in
simulating very small scale particle interactions. But you need at least as
many q-bits as there are particles being stimulated.

So this seems to limit utility to simulating nanoscale molecular
interactions, but AlphaFold is already quite adept at this, and is
improving all the time.

So what actual problems will quantum computers solve?
