Travel outside the milkyway is coming too. Timeframe unclear.

Agreed.

Ah, from your initial post I didn't realize you were a believer. Respectfully, I disagree. I've looked into the claim the scientists are making of why they think it "should" be possible. I have looked into their incentives. I have looked into what they are pointing to as progress. (Isolation improvements which don't prove the real question) I have looked into the wall of weasel words they hide behind. I'm just not buying it. They have not proven "it's coming." Much less when. If they get to the point of running shor on one real key (which I don't think they will) we will have plenty of time to deal with it before it becomes economically scalable to be a threat. "But what it there is a secret super quantum computer?" C'mon. That's silly. If I am wrong and it happens, then we switch to those garbage PQ algos, bloat the crap out of everything we are doing and take the security hit of leaving our battle tested algos behind. Until then, just say "no" to masking up for quantum covid and taking PQMRNA injection in our tech.
