Having written a significant number of lines of assembler early in my career, I am happy to delegate the task of register allocation (an NP-complete problem) to a compiler. I don't miss that manual task, and don't think the rest of my career suffers for that. I also don't particularly miss worrying about malloc/free in my programs, nor having to write multi-precision floating point arithmetic routines.
