I think a lot of Haskellers just got tired of arguing. I know I do so way less than back then. But I am writing Haskell more than ever nowadays (even at my dayjob!)
I would generally categorize what I do as "backend engineering." The domains have been all over the place. Crypto, fintech, adtech, data engineering, SaaS, infra automation. Lots of Postgres and a bunch of other tech (Redis, Kafka, other KV stores).
The places end up finding me (usually through LinkedIn where I make very clear that Haskell is what I'm about).
It's been fun! I've met a lot of nice people, and I got paid to climb way over the Haskell learning curve. Can't complain :)
