For me it’s quantum computing - especially considering its impact on most current encryption methods

Reversible Computing

In theory, we could make computers consume orders of magnitude less power, enabling extreme miniaturization of systems.

I still don't quite get what this is. From what I've just read it's transistors with zero heat dissipation caused by zero-ing out the RAM.

So okay, we have perfect RAM which never needs to be zero'd out, and 1 can be easily be reversed to a 0 if we know the operation that yielded it.... but what is the actual computational benefit here?

For a computer to have reversible RAM, doesn't that mean we would need to store more computation in order to roll back operations (and again, why would we want to?)
