Great post. But something not expounded upon by the author, and not addressed much in the comments here, is that asceticism is not a binary. Sometimes you really have to get-shit-done, and in that case, yeah use something fully featured. But a lot of the time, you'd probably be better off accepting a bit of slowness and pain in order to learn more. It's the classic framework vs. scratch debate. Use the framework if you want to go fast, build from scratch if you want to get better.
