These are your 10x programmers.
Maybe 100x or more in Bertrand’s case.
It’s not about putting in 19 hour days or spitting out more lines of code or PRs or whatever.
It’s coming up with elegant solutions with broad impact that no one else even considered.
I don't even think such a scale works for the kind of brilliant solutions Bellard (not Bertrand) creates.
I don't think 100 1x programmers can create these solutions. So much gets lost having to communicate and coordinate people. And they would just accumulate cruft (and DX tarpits like other mention).
