What does this mean about the size (and thus feasibility) of a circuit required to factor a cryptographically interesting number, say, to be generous, RSA1024?

Off topic, but are cryptographers convinced that on the new gigawatt data centers RSA1024 is infeasible to factor? I gather that the fastest known algorithms are still too slow to factor it in reasonable time. But is consensus that there will not be improvements to these algorithms in near future?

Number Field Sieves are still the best method, and the techniques are three or more decades old with only incremental improvements. (Of course there might be an incredible breakthrough tomorrow.)

Are the bitcoins in the first wallets gone? No? I will assume it's still the best method without any irrefutable evidence.

Bitcoin uses ECDSA to sign transactions, not RSA.

In addition, selling information to a government on how to break either system would be more valuable than the amount of bitcoin you would able to sell before exchanges stop accepting deposits or the price crashes.

Honest question because one can find such claims very often on forums like HN:

Does there really exist a "feasible" way how some "lone hacker" could sell such information to some government and become insanely rich?

I know that people who apparently have some deep knowledge about how exploit markets work claimed on HN that "if you have to ask how/where to solve your exploit (i.e. you have the respective contacts), you are very likely not able to".

This latter observation seems a lot more plausible to me than the claim often found on HN that some "lone individual" would be able to monetize on it if he found a way how to break ECDSA or RSA by selling it to some government.

Yes. Start what's known as "a company".
