i have been a software engineer for 20 years and never had to implement any of this stuff myself in my career. the last time i did was in my master’s program in CS. in contrast i’ve had to implement custom memory allocators and many other non trivial algorithms which cannot be implemented in 10 minutes but take days to design and implement.
