Every AI wants to teach you. This one needs a teacher.
Pip knows nothing. Every sentence you say becomes a belief in his head, sloppy ones included. The examiner maps the subject and seals a paper against it before you start, but you never see the map. You see the next thing you could teach, and nothing past it. What you never reached turns up on the report card.
Ideas:
Press enter or space to select a node. You can then use the arrow keys to move the node around. Press delete to remove it and escape to cancel.
Press enter or space to select an edge. You can then press delete to remove it or escape to cancel.
A real lesson, replayed. The map only shows what is teachable next. Nothing taught yet, so it starts at the beginning.
