It's probably not unrealistic that a programmer who learns Vim well could be, say, 2x more productive in Vim than in, say, Nano.

Yet programmers who have used Nano were not (at least not significantly) scoffed at or ridiculed. It was their choice of tool, and they were getting work done.

It seems unclear how much more productive AI coding tools can make a programmer; some people claim 10x, some claim it actually makes you slower. But let us suppose it is on average the same 2x productivity increase as Vim.

Why then was using Vim not heralded from every rooftop the same as using AI?
