And things like Blender? Is 2.80 only 64 bit?
Maybe the game engines like Unity if it ever runs on Arm?
I suppose Android will be only 64bit?...

Re: Raspberry pi for coding on machine level?

also compiling is hard ,

compiling for speed or space can be conflicting and difficult - unrolling loops can help in some cases but not in others....
but in general a compiler is better than you .
