Once you figure out a rule it immediately becomes obsolete and you have to start over again.

I thought rule #1 was not confusing the end of the baby that is for inputs with the end that is for outputs.
As far as I know, that one doesn't become obsolete very fast. If so, we've been doing it wrong.
Hmmm... in my experience thus far, outputs come out of each end of the baby.
And then there are the occasional medicinal inputs on the output end.
Yes, we have solidly figured out the no rules part
