I’m totally with you here, it is a really invaluable learning tool. But similarly to science with “standing on the shoulders of giants”, we would not be anywhere if everyone started everything from scratch. Like, it’s okayish to reimplement a vector or something, but even a sort gets harder (especially if you want to make one that is performant both on a few element list and longer ones). And algorithms are just one thing, will you also learn into the totally foreign world of eg. audio processing?

Basically the only silver bullet for productivity increase is shared code. We just have to place higher emphasis on software correctness/quality instead of the functionality churn in certain parts of the software world.
