Well at least Moores law favours rust on compile time. So in that regard it seems like one of the less problematic language issues one can have - it’ll sort itself out. The same can’t be said for the issues on other langs
In my experience, C++ template usage will always expand until all reasonably available compile time is consumed.
Rust doesn't have C++'s header/implementation separation, so it's easy to accidentally write overly generic code. In C++ you'd maybe notice "do I really want to put all of this in the header?", but in Rust your compile times just suffer silently.
On the other hand, C++'s lack of a standardized build system led to the popularity of header-only libraries, which are even worse for compile times.
Moore's Law never sorted it out, even when it wasn't dead yet. Software always got slower quicker than the hardware it runs on got faster (as can be seen currently on ARM Macs, they felt incredibly fast in the beginning, but now software is starting to catch up and new Macs are starting to feel just as slow as the Intel Macs they replaced (looking specifically at you, Xcode)
