Ask HN: Betting on the Phoenix Framework

Hi everyone - long time Rails developer here. I've been building a project with the Phoenix Framework lately and am absolutely loving it.

The project requires a high number of Websocket connections and concurrency features - which technically speaking, makes Phoenix a great tool for the job.

My only concern is about wether there is a strong enough community to keep the project going for years and years to come. Jose Valim and Chris McCord have been doing an incredible job and I respect them to the nth degree.

My question to the community is twofold - does anyone have thoughts on the future of the Phoenix Framework, and has anyone made a gamble on an upcoming technology that turned out to be the right or totally wrong decision?
