These days, I don’t lament this at all. As I see it, people wanted to make new on their own instead of learning what was there. This is just how younger people are. As they get older they naturally want to learn how things used to be, and the cycle will repeat. They will be the ones lamenting, and the younger folks will make it all new.
I don’t remember who said it but: those who don’t understand UNIX are doomed to reinvent it poorly.
