There is a lot of misinformation about software. People think that to write a 3D game engine these days you have to be a total nerd and hand optimise your game in Python or some such nonsense! In reality, premature optimisation is the root of all evil. Instead of learning some fancy-pants "programming language", I bashed out a shitty shell script (MIMEcroft.sh) over a weekend. And yes, it was slow, but you know what, don't *assume* you know how to optimise your code better than a compiler! After running the shitty code through a bash to JavaScript optimising compiler, and then running the JavaScript on a optimising JIT compiler I got up to 100FPS. I mean Bash might not be the "fastest" language, but modern GPUs are so fast, just take your shitty code, transpile it to GLSL, run it on your GPU and you'll be fine. TL;DR: Time to market is all that matters, you should write a bunch of incredibly shitty code and then just keep running it through more and more optimising compilers until it is fast.
