I have a distant relative who was working in javascript as his main job. But he didn't know what typescript, coffeescript, or web assembly were; even though he was working with javascript as his primary language. Nothing he described or talked to me about gave me the impression that he was able to do any programming whatsoever.
But, he was 100% a "total frat bro". And of course he landed a job at Google. As a programmer. Am I jealous? Sure. Do I think he is capable of creating intricate things? Absolutely not. Do I think he will survive at Google for a long time? Definitely.
