I have not reached the burrito point yet.
I once asked my friend whether he understood Monads and could explain them to others. He sarcastically responded “No, I have not reached the burrito point yet.”, supposedly in reference to a paper that explains burritos as strong monads.
He defined ‘the burrito point’ as the level of understanding at which you can understand why a seemingly simple analogy is relevant with respect to a concept that is perceived to be hard to understand. More generally it can be taken to mean “an adequate level of understanding”.
