The incompetence of the mods is relevant because it is one of the main criticism of TFA. It's a nice example of the Pete principle.
If a mod doesn't understand an answer he should just pass, not vote according to what's right most of the time. They are incompetent, both regarding LuaJIT and as moderators.
I'd expect mods familiar with Lua to recognize him, and he should have mod powers, to begin with.
Again, if he had just used his original account to edit his answer, he wouldn't have needed any of that.
He's a world class expert in compilers and high performance, low level programming on modern hardware.
This addresses the core point of the article, being that the SO "meritocracy" is badly implemented, and conflates heavy site usage with maturity and technical ability.
Edit: If not a mod status, a VIP status. SO would gain a lot if its staff were to individually recruit people as talented as he is.
If it allows it, and delegates the check to moderators, then these moderators should either reject it if they are sure the change is wrong. In all other cases they should allow it.
It's really that simple.
The heuristic they use is something along the lines of "only accept edits that are grammar fixes, equivalent thereof, or rewordings". Content changes without the authors consent are considered poor form.
