The invisible boundary between what AI can and cannot do. Coined by Ethan Mollick and co-authors in a working paper based on experiments with consultants. Tasks that seem equally hard can land on opposite sides. Idea generation: easy for AI. Basic arithmetic: surprisingly not. Without extensive hands-on experience, you won’t know which is which until it’s too late.
