Yeah an important lesson for programmers is that for big projects the ecosystem around a language is usually more important, for any given metric (productivity, quality, performance), than the language itself. Python being used to do high performance math all the time is a good example of this. Python the language isn't at all good at that, but the ecosystem has nice libraries with high performance C code underneath them. If one comes to believe there is a language that really is a lot better, then you have to get to work building out the ecosystem around it to realize that, and it isn't easy!
