So sad to see he is leaving Clojure community. That's a sign of the death of Clojure. A few great developers have moved their focus away from Clojure.
Where are you getting this information from? Phil works for CircleCI, who have been very open about how much Clojure they use, and his GitHub profile indicates anything but: https://github.com/technomancy .
The reports of Clojure's death have been greatly exaggerated.
Mainly from people who just want the language to fail for some reason.
From the looks of things he recently joined CircleCI which is using Clojure, so maybe not all is lost ;-)
