Yeah, I mean, I can't speak for him, but one thing that I guess we should note is that Scott is primarily a theoretician.
So for a very long time, he was working on the theory, not so much on the day-to-day of quantum computers.
And I think that was partially the reason why he was so hedged.
I think what's happening more and more is that there's like real companies, real entrepreneurs building these things.
And he has an insider view and he's basically ingesting all this information.
One of the things that he said recently is that the US government is starting to intervene with the publication of ideas.
What if you could trade gold, forex, and global markets with the same tools and speed that you use for crypto?
Yeah, so there's like multiple relevant metrics.
There's the total number of physical qubits.
There's the total number of logical qubits.
And there's also the total number of steps it takes to run the algorithm.
And this has a real impact because it's going to determine if it takes a minute to break a key, a day, a week, or a month, or a year.
Yeah, so roughly speaking, the number of physical qubits to get one logical qubit today is a few hundred, call it a thousand.
And what should happen is that the quality of the physical qubits, the so-called fidelities, should increase.
And also we should come up with better erasure coding codes that will basically improve this ratio.
So it's possible that in the future, we'll only have 100 physical for every logical one, or maybe just 10.
So that's going to improve.
And then when you look at the algorithm to break the discrete log and ECDSA, roughly speaking, it's a small multiple of the number of bits in the curve.
So we're working with this curve called
