I don't use it at all for a variety of reasons, but I rarely bother to get into discussions on HackerNews.

Looking at how new it is, and how quickly things are changing, it seems likely that I could adopt it into my workflow in a month or two if it turns out that that's necessary.

On the other hand, I've spent the last 2 decades building skills as a developer. I'm far more worried that becoming a glorified code reviewer will atrophy those skills than I am about falling behind. Maybe it will turn out that those skills are now obsolete, but that feels unlikely to me.
