Maybe they will! Are you expecting them to live-tweet their work or something?

jared was OK making this rewrite as an experiment branch in the public

why shouldnt upcoming work be as public as the rewrite itself was?

I'm not sure Anthropic even cares about "releasing" the next version. The rust one has been in use in Claude Code for more than a month now, used by millions of people, and that's as far as they probably really worry about it. They bought Bun for Claude Code and I doubt the open source project matters to them otherwise.

I very much doubt they would want to abandon the wider community. They do benefit from others using it.

To the contrary, I think any problem with this release would be jumped on harshly so they're being more careful than usual. There's not a rush for the community to move to 1.4 and any issues could poison the community trust.

I didn't follow the thing too closely when it happened. Sure, I was aware of the big picture. But wow, I didn't expect that after all this noise there still hasn't been a release? That's just crazy to me. I shouldn't be surprised though, of course. Giving any credit or slack to a high-valuation LLM company is a silly endeavor.

It was expected. These LLM rewrites seem to work amazingly at first and then you realize there is a ton of work remaining.

Many repeat the point of “$165k is cheaper than team of multiple engineers working on the rewrite for a year”, which I think is flawed — the team of engineers would have produced idiomatic rust, and it would take probably 100k+ of tokens more to make the bun in rust idiomatic rust.

> produced idiomatic rust

I keep seeing this. What is "un-idiomatic" rust?

I feel your estimate of tokens is a few orders of magnitude off, it’s on the low side. I use more (albeit cached) when centering a div.

This is where we've come to where people proudly proclaim using an AI to do what is a single line of CSS.

Author here: An apology on the graphs, they just count rust files touched in commits, not total commits. So if there were two commits and one touched 3 .rs files and another touched 2, it'd be counted as 5 for the purposes of the graphs. I may fix this later but, yeah.

Hope you find that job :) nice work experience, looks very ethical focused.
