I used to be one. I’ve also been a 1/10x programmer. Knowing and mastering your tool chain, language, editor infrastructure etc intimately; can have tremendous productivity gains.

Health issues also take away a lot. Kids getting old enough to not require constant attention is allowing me to regain some of that.
