I'm with you on the increasing complexity of code. That goes along with what I said about enterprise and global scale.

But loss of knowledge? Really? DNS is not some arcane knowledge limited to an inner circle who was there when it was invented. You can literally read RFC 1034 and RFC 1035 and know everything you need to build a basic working DNS server or client. The concepts are literally taught in every university course about networking because they are that important.
