But who cares if they gain traction? I don't need it to gain traction for me to be able to make use of it correctly and efficiently. In fact, I probably need the opposite, for it to not gain traction, so I can focus on using it and improving it for myself only.
gist was certainly not implying that it was not possible to do it or that some people won't continue doing it but the point was rather that the pool of such people or such projects will significantly decrease because software has now (mostly) reached the abundance state where all of these technical details start to matter less and less for general consumption.
Libraries, languages, and all that good stuff are the stepping stones we use in service of building powerful abstractions that can then be used to expand software complexity. You cannot LLM your way out of that, I’m afraid.
