> we have so much better dynamic languages with advanced JIT implementations
What are some of these better languages that you're referring to? (The usual dynamic language JITs I hear people praise are LuaJIT and Chez. And V8. And the JVM?)
Smalltalk, Self, whose research lead to Hotspot and V8, Common Lisp.
And the usual, in Python everything is dynamic, well it is even more so in an image based live coding environment, where any break into the debugger, with code changes and resume execution can come back to a complete different world.
Additionally there are features like Smalltalk become: message, where two objects can change places everywhere they are used in the image, and current execution.
I'd suggest F#, Clojure, Elixir, Scala, and TS, if that counts.
Clojure could never really be a thing since it ignores the most important rule: fast startup. Because of this, and for no other reason, Clojure will always be an "also ran". It's not about competency of the people working on it. It's a solvable problem the community doesn't acknowledge exists, unless you press them on it, in which case they think "graal" and "babashka" is a valid response, and you're back to square 1.
Even Ruby has JIT now
True! But pjmlp was referring specifically to advanced JIT implementations, so I wondered which JITs he was referring to as advanced.
In Ruby's case that would be RubyMotion, TruffleRubby and JRuby.
That trace back to Apple's efforts with MacRuby, or Sun's (for a while Netbeans even had Ruby support).
