Jibe means to be in accordance. Jive is a dialect and a dance. FYI. I realize we will probably lose these words, but for now.....

I get your point, but at the same time I would say that it's often much harder to "do better" when you don't even have a clear idea what it is you're trying to improve upon.

They are not saying you cannot be better. They're just saying to respect what came before and learn from it as you devise the better scheme.
