I have a very high IQ. I tested off-scale on every intelligence test I ever took.

That means I am very good at taking IQ tests, pretty good at a very few other things, of average ability for many things, and very poor at quite a few.

I suspect that many so-called “geniuses” are just like me. The fact that I know that means that I am much smarter than Elon and his gang of teenagers.
