You're getting downvoted, but this was what tptacek basically wrote about. Key points from his blog are that LLMs are good at tedium, and Go's structure is highly repetitive and amenable to LLM generation. The error handling tedium is probably part of why it's highly repetitive.

> I work mostly in Go. I’m confident the designers of the Go programming language didn’t set out to produce the most LLM-legible language in the industry. They succeeded nonetheless Go has just enough type safety, an extensive standard library, and a culture that prizes (often repetitive) idiom. LLMs kick ass generating it.
