I agree, but this is very tricky in the software development industry where things change so quickly. I went from senior to leading a team of 5 people. As soon as I started to lead, my technical skills started to atrophy. I've now switched companies and dropped back down to a Senior position because I need to build my skills back up. How do you navigate this?
If you know fundamentals things do not change that quickly. True paradigm shifts (such as FP) that require ground up revisit of internalized knowledge happen at a fairly stately pace.
