> Ruby is an interpreted language released in 1996 for scripting. Why are we surprised when attempts to shoe-horn it into something else (Ruby 3.0, JRuby, Truffle Ruby) fall flat?

Because Lua (1993) and JavaScript (1995) can be very fast.

To be just, Lua is drastically simpler as a language. A simpler language likely takes less effort to write an efficient JIT for its VM.

And javascript's speed seems mostly a result of throwing amazing amounts of smart engineers at it over time, rather than anything inherent in the language itself.

How is the state of LuaJIT since Mike's departure?

I don't follow Lua, but I got the feeling it is pretty much stuck on its last version.
