I am actually on a lookout for a low level language which compiles to web assembly to write a (relatively small) supervised learning model which I plan to be good enough for 5 year old phone CPUs. I have a working prototype in Julia and was planning on (eventually) rewrite it in Rust mostly for the web assembly target. I come from a high level language background so the thought of rewriting in rust is a little daunting. So I was excited to learn about Mojo and find out if they had a WebAssembly target in their compiler.

But then I read this:

> AI native

> Mojo is built from the ground up to deliver the best performance on the diverse hardware that powers modern AI systems. As a compiled, statically-typed language, it's also ideal for agentic programming.

Well, no thank you. I know the irony here but I want nothing to do with a language made for robots.

I’ve written Python for the past 25 years or so. I dig it. But I don’t think I’ve started a new Python project since starting to experiment with Rust. A lot (not all!, but a lot) of Rust patterns look a lot like Python if you squint at it just right. I also think that writing lots of Rust has made me better at writing Python. The things Rust won’t let you get away with are things you shouldn’t be doing almost anywhere else.

Go on, give it a shot. It stops being intimidating soon! And remember that the uv we all love was heavily influenced by Cargo.

I actually have written Rust, but it has been a minute. I think my last project (a backend for a massive online multiplayer theremin jam session [site no longer up; but HN discussion still exists: https://news.ycombinator.com/item?id=10875211] 10 years ago).

I remember Rust very fondly in fact. And I had the same experience as you, learning Rust made me a better Javascript programmer. Lets see if a little neural network can be as fun.

If you’re searching for a language that has the same strong memory safety than rust but is a bit easier to write, you should give Swift a go.

Good call. It’s not the first language I think of for most things but there’s no great reason why not to. I probably reach for Rust first because I’m more familiar with it and the projects I want to work on were already written in it.

I can't go get coffee so many times per day, there are better compiled languages to chose from, while offering Python like ergonomics.

I can only go get coffee waiting for my Python test suite to finish so many times per day. I write Rust because the strict type system accelerates the iteration speed for producing correct code more than any other language in its class.

Which is why the solution is to pick neither, rather something with Python like productivity and a mix of JIT/AOT tooling.

Some alternatives are as old as 1958.

Mojo has been suffering in their communication from targeting VCs rather than users. They never actually had a clear "Mojo extends Python" MVP or even strategy to get to an MVP anytime soon. And the language started developing before AI Agents were a thing and has more to do with building around state of the art LLVM tooling than AI Agents. But I guess "easier lifetime semantics than Rust and native access to MLIR intrinsics" doesn't raise money...

Might want to take a look at WasmTarget.jl it’s rather new and experimental but could be what you’re looking for!

Too much vibe code for my taste.
