alt Hacker NewsThe question then is how they plan to avoid The Lisp Curse (in my words, language giving you too much power makes you do weird things, and you attract people to like to use things a tad too powerful / generic, and you end up with an unproductive culture).

Practical Lispers would like to have a word - I've been witnessing extreme productivity on some teams.
Modern Lisp dialects (Clojure and likes) largely broke library fragmentation and the "not invented here" tendency that were causing real tensions in Common Lisp.
You realize that "The Lisp Curse" isn't some paper, survey or objective reflection? It's just someone's essay back from 2011 - an opinion.
You can take it word-by-word and apply to say Javascript, and it would largely feel true - JS arguably has the worst fragmentation of any ecosystem; dozens of competing frameworks, build tools, bundlers, test runners; new frameworks constantly replacing old ones; "Javascript fatigue" is a real thing, etc., but nobody talks about "Curse of Javascript"
I learned Lisp (once) and that opened up path to Clojure, Clojurescript, then Fennel, Janet and Clojure-Dart, libpython-clj, there's Jank that is about to break loose. And something opposite to fragmentation happened to me - all these incompatible runtimes became unified and controllable from the same substrate - I no longer feel like I'm having to switch between languages - the syntax and thinking stays stable. The runtime is just a deployment target.
The curse essay says: "Lisp empowers fragmentation". Actual experience says: "Lisp provides unity across fragmentation that already existed"
Then again sometimes things don’t need to have productivity as a goal do they? Scale and context applies, could be seen as art even, an expression of someone’s psyche and their world model
The primary culture around Lean is mathematicians looking to prove mathematics. AFAICT Lean is just about the right power for that.
Agda, OTOH, is IMO the dependently typed language for type theorists, and does weird things, but "unproductive" is applicable only for a somewhat narrow view of productivity.
I don't consider there to be a dependently typed language for writing programs that you just want to run, but I would be delighted to be corrected on that viewpoint!
