> it's impossible for a dumb person to pretend they're smart.
Unfortunately, that's not true. It's actually pretty easy to convince dumb people that you're smart, and so even dumb people can learn that skill. Myriad successful careers and even entire industries have been built on that foundation.
I can think of a couple of presidential careers where that worked out for the deceivers.
The truth is you can build a successful career, on a foundation of a successful industry, that is run for and run by, all idiots.
