I appreciate you revising your reply to be less harsh, I wasn't aiming to correct you on anything I was just offering some thoughts, I find this stuff interesting and like to chat about it. I'm sorry if I made your day worse, I hope things improve.

I said superconducting semiconductors as just a handy wavy way to refer to logic gates/transistors in general. I'm aware that those terms are mutually exclusive, but thats on me, I should have quoted to indicate it as a loose analogy or something.

The only thing I disagree with is your assessment that computation doesn't create heat, it does. Albeit an entirely negligble amount, due to the fact that traditional computation involves deleting information, which necessarily causes an increase in entropy, heat is created. It's called Landauer's principle. It's an extremely small proportion compared to resistive loss and the like, but it's there none the less. You could pretty much deal with it by just absorbing the heat into a housing or something. We can of course, design architectures that don't delete information but I'm reasonably confident we don't have anything ready to go.

All I really meant to say is that while we can theoretically create superconducting classical computers, a room temperature superconductor would mostly still be used to replace current superconductors, removing the need for liquid helium or nitrogen cooling. Computing will take a long time to sort out, there's a fair bit of ground to make up yet.
