I've watched a chess-lecture on youtube 2 days ago. It was exactly about that.
The thing is: You need to know how to follow up after you have developed and your opponent hasn't yet.
Actually it's a pretty simple principle once again: Open up the position (mostly by exchanging pawns).
If you don't do that quickly, your opponent will eventually catch up in development and all the advantage you had from your early development is in vain. Behind inpenetratable pawn walls it doesn't really matter that much how developed the position is.
In chess the attacker wins. So sooner or later you'll have to do something with your better position. Tricky computers exploit that and force you to do something about their "bad" play. That usually involves tactics and that's what they want.
