The thread was written by a VC on what he thought a “10x Engineer” to him was, and he grossly summarized pretty much the opposite of that. https://twitter.com/skirani/status/1149302828420067328?s=21
Here's an actual quote from the thread: "10x engineers don't hack things. They write quality code and know exactly how the code has to evolve, and have a mental model of overall code structure. They write at most one design document, and the rest is in the code."
The thread wasn't particularly crazy as far as Twitter takes go. I think it only went viral because of tweet #3, the one about background colors and keycaps.
The whole meme about 10x programmers writing terrible code very fast must have come from somewhere else.
