Yes, Datomic is the killer app for Clojure [^1]. Have a look at Datascript[^2] and Mozilla's Mentat[^3], which is basically an embedded Datomic in Rust. Hickey's Spec-ulation keynote is probably his most controversial talk, but it finally swayed me toward dynamic typing for growing large systems: https://www.youtube.com/watch?v=oyLBGkS5ICk https://www.youtube.com/watch?v=oyLBGkS5ICk The Clojure build ecosystem is tough. Ten years ago, I could not have wrangled Clojure with my skillset - it's a stallion. We early adopters are masochists, but we endure the pain for early advantages, like a stable JavaScript target, immutable filesets and hot-reloading way before anyone else had it. Is it worth it? Only if it pays off. I think ClojureScript and Datomic are starting to pay off, but it's not obvious for who - certainly not very ever organisation. React Native? I tore my hair out having to `rm -rf ./node-modules` every 2 hours to deal with breaking dependency issues. Whenever I try to use something else (like Swift), I crawl back to Clojure for the small, consistent language. I don't think Clojure is the end-game, but a Lisp with truly immutable namespaces and data structures is probably in the future.
