obviously decades of security advisories means it's not easy. what in the world does 'easy' mean in your current usage? surely "tons of failures" is a better indicator of difficulty than "it feels easy to me / that's 'naturally how my brain works'," etc.

and of course, if lots of people fail at something, it will get proportionally harder with a larger team / larger codebase / different stakeholders demanding xyz, etc etc etc.

not chiming in about the basic disagreements in this thread, but the repeated claim that something that has caused trouble for countless professionals is "easy" just can't be right. if all the qualified people are "unqualified" because they all fail at something "everyone can do," the speaker is the one who's confused, and it's a lexical problem.
