I'm someone who likes to write Rust and wants to use it all the time, but for my professional work I only choose it when I really need it, which is very seldom - actually it was only once for a CAD data converter where memory usage must be as low as possible. The reasons not to use it always for everything are: 1. The mental overhead is larger than most want to admit. It's not about the syntax, but about memory management of course. The time and effort spend there should be spend to solve the problem at hand. 2. Depending on a lot of third party libraries which are maintained by just 1 person.
