Incompetent, irrelevant, and immaterial!
It’s funny. Do you know the puzzle of the farmer who wants to transport a fox, a goose, and some grain across a river on a raft, but he can only carry one of these at a time, and he cannot leave the fox and goose, or the goose and grain together? How can he do it? Of course, it’s a schematic problem, and one can raise all sorts of quibbles and qualifictions to the problem as stipulated, as I learned first hand as a youth.
My dad built a physical model of the problem with the farmer, fox, goose, and grain represented by pegs, with each side of the “river” represented by four holes for each of the pegs. You had to pull out the pegs simultaneously ( i.e. the farmer and one other ) or else it would buzz, and this was actually a fatal complication for the intent of the project, although occasionally he could do it. This was just straight wiring with a battery and a buzzer.
So what I’m saying is, you gotta go with it, you know?
First lesson!
When teaching Chess to kids I used that problem and the kids had to solve it in their heads then tell me how they did it. The key is that the farmer can come back empty to the original side ... take fox over, go back get grain, take fox back and pick up goose, take goose over and pick up grain and bring back, then pick up fox and take over and bring back grain, then return empty and bring goose over to where grain and fox are waiting ... except the goose would wander off when the grain is gone anyway.
