Your counter argument would be valid for a 2000 or a 2020 business decision about some tech stack.

This is a spectrum, it's not just 0% vs 100%. Even Fable frakked up a few things really badly in my professional work (though to its credit after a very detailed 2h chat it self-corrected and fixed all the blunders).
I would also challenge "fast" -- Fable (and I assume Mythos) are wicked fast and efficient and even they can't compensate for f.ex. slow recompilations or test suite reruns or security scans, linters etc.
Reminder that the Bun's Zig-to-Rust rewrite took 11 days with dozens of agents working 24/7 and the author put the cost they'd pay (if they had to pay) at about $168k.

And GP is full of shit as the main branch is the v1.4.0. it is not "released" yet as it is not finished. It is available as canary version.
So Anthropic ships with unfinished version of bun. Doesn’t sound like responsible software deployment

Eh, the rendering of Claude Code is genuinely such a mess. I have quit claude code over it because when used as a terminal in PHPStorm it sometimes gets so bad that it becomes hard to use. This isn't a minor nitpick, it's a pretty major UX issue. Not saying it's like a massive business downside because I'm just one of a few users, maybe this affects their bottom line a little bit, but probably not by much. Regardless…
> when used as a terminal in PHPStorm Truthfully, the terminal in Jetbrains IDEs just isn't that great. It's gotten a lot better with their rewrites (yes, plural) of the last years, especially on Windows, but it can still be pretty dodgy.
That may be so but Claude code certainly has rendering glitches in other terminals too.

They succeeded in spite of their tech choices. Their model outshone it, which is an extremely rare thing to happen and not something they could've counted on. In any other timeline they could've/would've been hurt by their choices. It's like "why did you go all in on buying scamcoin 3.0 as your investment strategy?" -- "I 5xed my money! End of story! It was fine!"
> They succeeded in spite of their tech choices. Or those choices just don't matter, it's fundamentally just "tabs vs spaces".
As much as an enthusiast dev like myself hates it -- this is innately true, way too often.
I am 46 y/o and still excited to code and solve problems with code and I still have trouble to admit to myself sometimes that people make dozens of millions with PHP and the tech hardly matters when you can throw bodies at the problem (and when that throwing of bodies at the problem actually solves it, of course).
Re: Claude Code uses Bun written in Rust now
#346All the emotion of speculations aside, how it runs? It boots faster yeah, but what about RAM and CPU usage? Weird dead loop or dead locks? If it run as good as before or even better, then that's kinda impressive. I'm a developer so I really don't like it when AI might took my job, but if everyone on this planet could create a software for themselves exactly as how they wanted with just a few simple demands, that will…

It's not even about requirements. It's about responsibility. Someone has to take responsibility for the code and the product. Someone has to hotfix a bug that's costing millions of dollars an hour and someone has to be blamed for a bug that's consting millions of dollars an hour.

Code is the killer app for LLMs so software developers are the easiest to replace.
Code isn’t what the majority of software engineering is.
Pointless nitpicking that completely missed my point. Software developers are not the hardest to replace, so your presumption that everything else should be easier is wrong.
Re: Claude Code uses Bun written in Rust now
#348It's a transpile. And not even a good one. The generated code is far from idiomatic rust. Some may consider it an abomination.
given enough time and tokens, it will become that. I really don't understand how that is a problem in any way.
Re: Claude Code uses Bun written in Rust now
#349Maybe I’m taking crazy pills, but I’m still stuck on “why the hell does a TUI need to run in terminal React by way of JavaScript” The fact that Anthropic felt the need to buy a runtime so they could make their TUI better speaks more to the quality of engineering than anything else IMO. If rewrites are so easy, why not rewrite CC in a native language? Would’ve been a hell of a lot cheaper.

Claude code still can’t handle scrolling history without corruption. It is embarrassingly broken.

grep -nr 'unsafe' . Is all you need to know to consider how much of an abomination it is
The original code was one giant unsafe block with almost no tangible way to find or debug all the subtle memory bugs and leaks they had. Now it's smaller, faster and has fewer bugs. Also its every potential memory issue is neatly annotated by an unsafe block so you can go and refactor them out one by one with confidence. All this seems like a pretty huge improvement to me. Why is this an abomination in your eyes?
> has fewer bugs
who claimed that? Are you suggesting that the rewrite did not introduce any new bugs? The correct answer is, by the way, that no one knows since it's millions of lines of code no one has properly read.
> smaller, faster
I thought this has already been debunked. You could just write better zig and make it smaller, faster (and have fewer bugs!)
