I don't speak for Phil, but I do work with him at Lumi where we use PureScript for almost all frontend. It's been really fun to show that PureScript can be used successfully in production.

You can see some of our tutorials and open source projects here: https://www.lumi.dev

Life! :)

He still uses PS and chimes in on some issues, but doesn't really have time to work on the compiler anymore: https://twitter.com/paf31/status/941745900426215424

Like many of us, he had children and couldn't keep up with the workload, so he took a step back. Fortunately there is a very active community working on PureScript!
