When everyone is a superhero, there will be no superhero. When everyone leetcodes, it is time to get back to fundamentals. So I agree with the author: grab a book, study fundamentals. Instead of memorizing 10 different dynamic programming problems, do study dynamic programming -- it's fun and it is useful in production code anyway. Instead of bitching about finding a shortest path of whatever criteria on a tree, do study backtracking. Instead of agonizing over how to build a LRU or a token bucket, build a LRU and a rate limiter. Instead of pulling your hair on implementing a concurrent queue, study The Art of Multiprocessor Programming. The list goes on and the process is fun.
