In pi’s case there is a plugin system. It’s much easier to make a self extending agent work with Python or JavaScript than most other languages. JavaScript has the benefit that it has a great typing system on top with TypeScript.
replyFor a TUI agent, runtime performance is not the bottleneck, not by far. Hackability is the USP. Pi has extensions hotreloading which comes almost for free with jiti. The fact that the source is the shipped artifact (unlike Go/Rust) also helps the agent seeing its own code and the ability to write and load its own extensions based on that. A fact that OpenClaw’s success is in part based on IMO.
replyI can’t find the tweet from Mario (the author), but he prefers the Typescript/npm ecosystem for non-performance critical systems because it hits a sweet spot for him. I admire his work and he’s a real polyglot, so I tend to think he has done his homework. You’ll find pi memory usage quite low btw.
OK, make sense, but there are also claw clones that are in Rust (and self modifying).
replyAlso python ones would also allow self modifying. I'm always puzzled (and worried) when JS is used outside of browsers.
I'm biased as I find JS/TS rather ugly language compared to anything other basically (PHP is close second). Python is clean, C has performance, Rust is clean and has performance, Java has the biggest library and can run anywhere.
