JVM has real and virtual threads and arguably just as good if not better on all these points.

(I actually have/am writing a harness in Java fwiw, but mostly as a hobby/experimentation)

JVM apparently has the disadvantage that nobody under the age of 40 wants to touch it anymore. I admit I haven't worked in it in 20 years, but I do think it's a marvel of engineering and unfairly maligned. It used to be my career but I wanted to be closer to the metal.

Having Oracle's tramp-stamp on it may have been the final kiss of death in terms of totally-superficial "coolness" factor.

The JVM has a fixed size heap which for me it is wasteful.

IMHO, Microsoft made the correct approach on .NET.

For LLMs, I prefer C# and C++ instead of TypeScript, JavaScript or Python as the static + compiled language factor keeps the coding agents on track. Plus, they have a true threading/async implementation.

		It's only appearing wasteful if you're not understanding how memory management works on modern operating systems. It's not wasting any RAM at all if you pay attention to RSS vs VSS. The actual physical RAM is still entirely available to other applications. It's just made the OS know it might want that many pages. Until there's data in the pages, they will not count towards total RSS. It's the kind of things some sysadmins used to gripe to me about and I would question whether they should be in charge of a machine at all. To repeat: just because an application mmaps a large region doesn't mean the OS has actually given it all that physical RAM. It's merely made sure the pagetable knows about it.

and you could say the same if not better from C#. But those are now becoming niche languages and ecosystems. One for people around microsoft, azure, etc. The other around oracle solutions. There are still pretty interesting projects around it any of them, but they seem to be losing mindshare against other languages.

		nah, C# is huge in game development and things adjacent to it. Lots of young people know it and love it for that reason.

But have you considered that java is gross and nodejs is sexy?
