I think the secret is slightly different. Most think they can fully solve a problem. Such that their solution is the one everyone should use.

This manifests in assuming everyone can afford the abstraction boundaries chosen. Or that everyone needs the same tradeoffs. Or, ultimately, that everyone would come to the same conclusion.

I think of it as the desire of most people to boil software down to formulaic choices. Imagine if you came up with something as elegant as "F = ma" for software.

I feel this is somewhat related to the rise in functional programming. It is not that either of those things are bad goals to chase. But they are not ends to themselves.
