> There is a lot of debate over the definition of intelligence but one thing most definitions have in common is that it is general. A human being can play the piano, solve an integral, write a novel, compose a photograph, and many many more things.

There is a nice paper on this topic.

On the Measure of Intelligence - François Chollet https://arxiv.org/abs/1911.01547

I believe generality in human intelligence is overrated. We can't do large multiplication in our heads, we can't solve the Salesman problem in our heads, and many other things we can't do because our intelligence is not in fact general. It has a set of skills and can combine them in many ways.
