> I don't care about the headaches people had 20 years ago Hard disagree. Especially with technology, what we have today doesn't usually make much sense unless you compare it with what we used to have: everything started out the simple, but naive way, and evolved out of combat-tested lessons learned to what it is right now. If you don't know what those lessons were, a lot of the design decisions that went into what you see will seem mysterious and, possibly, pointless.
