I take issue with the idea that going down the rabbit hole is an inability to stay focused. If you don't chase these things to their resolutions, how will you ever learn how to get maximum value from Typescript?

Note that I agree with the author that Typescript doesn't help as much as it costs (you can glimpse one of my rabbit holes here https://betterprogramming.pub/reverse-engineering-typescript-types-21196a97a0f6), but most of us don't really have a choice about whether we're going to use TS or not, and I find that usually these types of diversions pay for themselves fairly quickly in increased understanding and confidence.

But I did laugh out loud at "burning other people's money" haha
