I'm a front-end dev. I play with CSS until it's close enough to the design I can get someone to sign off on it. I write tests too, and that doesn't take much. My tech lead is literally afraid of switch statements. I've had coworkers not understand for loops and reject MRs. I still prefer using if statements instead of X ? Y : Z.

I'm pretty dumb, and I make 120k USD writing code.

Sure it's possible to be too dumb, but that's Forrest Gump levels of dumb.
