Java (incl. Scala, Closure, Groovy, Jython, etc.) is better suited to running as a server. Let agents write clean readable code and leave performance concerns to the JIT compiler. If you really want you can let agents rewrite components at runtime without losing context.

Erlang would offer similar benefits, because what we're doing with these things is more message passing than processing.

Rust is what I'd want agents writing for edge devices, things I don't want to have to monitor. Granted, our devices are edge devices to Anthropic, but they're more tightly coupled to their services.

There is literally no reason to write it in a JVM language in 2026 when better options exists. Either Go for simplicity and maintaininability or Rust to get the most out of the machine works.

Also, it'll be hard for them to lure good people to work on that thing. Absolutely no one is getting excited to write, vibe, or maintain Java.

I am not thrilled to use java, but it really does what it says on the tin. A customer copied the jar file I sent them to their as400 and it just worked. There is nothing quite like it.

Go binary says hello. No VM overhead. Everything is statically linked.

Hi go binary, unfortunately you don't exist, because there is no cross compiler for that platform. Also please don't crash if you ever do get cross compiled, since the target system doesn't understand your utf8 strings.
