I worked with c++ for many years and it has lots of warts. Slow compilation, lack of decent build system (no cmake isn't that great), mistakes made in the standard library (iostreams), weak cross platform standard libraries were always a headache. But I always loved the power that <algorithm> and the like provides, although attaching allocators (and other template things) kind of sucks.

When I looked at and test drove rust all I saw was heaps of complexity stacked up yet again. Probably didn't help that I smacked headlong into the Arc Mutex and lifetimes mess. I'm really more inclined to go for something like 'zig' which does so much with simple syntax (and awesome comptime) and still gets excellent performance.
