I’d love to extent this reasoning to other machinery.

A child can lift ten pound objects, and a crane can lift ten pound objects. A child can speak, so surely a crane can speak.

I think multitasking is the mental trap. People seem to do better reasoning about unitasker tools.

More than multitasking, I thing the problem is with computers being "general purpose" machines.

Also, to someone who doesn’t understand how a crane works, it’s use and function are somewhat apparent by looking at the machine.

A computer doesn’t look like it does any particular thing. If it can do surprising thing A, what about surprising thing B? C?
