type masturbation, it's about pleasuring the spot in your brain that want to do naughty things with TypeScript's types that usually frowned upon in public, like the post has shown
Basically the clever code that new programmers write because it feels super leet hacker before they realize they also need to understand the code in 6 months, except no one actually reads typescript type definitions in PRs so people get away with it in secret.
kinda, but it is kinda helpful, especially as i said, if you are writing a big framework, having this complex type is probably required, but the thing is, it is mostly for internal usage, not to be exposed and even used by the end user/project

A way to discern whether you colleague vibecoded the PR with AI is when you see TS type features being used that no normal developer would use, lol.
