Yes, I'm gonna talk about Julia...

It's kinda of sad how much effort is put on the creation of new Python compilers to make it slight faster while the problem of latency to compile that people hate at Julia is not tracked because of the lack of manpower to improve Julia's interpreter.

https://youtu.be/IlFVwabDh6Q?t=2530 (tldr: The Julia interpreter is currently about 500x slower than JIT code and there are a lot of low-hanging fruit work there that could easily give it a 10x speedup - this could make more viable to switch between compiler and interpreter depending on the work)
