OK, they've got a working prototype, congrats! Now it needs to be put into shape so that all the unsafe blocks are eliminated (maybe with a few tiny exceptions), and the code is turned into maintainable, readable, reasonably idiomatic Rust.
I wonder how long is it going to take.
I just want to comment that I think it's a good change if we look past the AI involvement. Bun has had an extremely high amount of crashes/memory bugs due to them using Zig, unlike Deno which is Rust. Of course, if Bun's Rust port has tons of `unsafe`, it won't magically solve them all, but it'll still get better

Just a cautionary case of porting to Rust using AI https://blog.katanaquant.com/p/your-llm-doesnt-write-correct...
if you give just the logical tests, it wont consider the speed at all. if you included tests that measure the speed and ask the llm to match the performance, itll do that too.
its the same class of error as everything else with llms. it has no common sense context for things people consider important. if you dont enforce the boundaries, it will ignore them

Looks like he did the maintainability performance and test suite checks and made his decision :)

> why: I am so tired of worrying about & spending lots of time fixing memory leaks and crashes and stability issues. it would be so nice if the language provided more powerful tools for preventing these things.
Not a hard number obviously but a clear indication those issues exist.

6 days of work to do this. Even if it doesn't end up becoming meaningful, it shows just how tokens and work done will be linked now and in the future. It's going to be hard to compete with someone or a company that has more compute. They will just be able to do things you can't.
You could have said the same thing about steam power or electricity. And it’s not just an analogy: The magic of these things is in being universal information engines. You spend capital to build them, using well-understood, scalable techniques, plug them into electricity, and out comes value. My point is, there’s no chance of a “haves and have nots” emerging, any more than electricity turned out that way in the moder…
Energy costs vary widely across the world and that has enormous capacity for the economies of different countries and their industrial capacity.
