Also, in my experience, Haskell's user experience isn't all that bad. It seems to me that the author is worked up and dense for some reason, and is hoping that a custom base library will somehow help. All the advertised features on the website (https://neohaskell.org/) are already in Haskell's base library or an import away. The "coming soon" "Pre-thought architecture" isn't, but I'm doubtful that there exists a single architecture that fits every problem.
Scientifically, it's cool of course, dependent linear types yaay.
Socially though, incompatible rewrite in Scheme should've been a separate project IMO; but since it's called "Idris 2", community attention faded away from the Haskell implementation "Idris 1". Which caused bad maintenance, neglect, stagnation, of a thing I tried and liked.
