#292Earlier quoted context omitted.
Search for pointer exceptions or core dumps on Bun's GitHub issues and you'll see why people (should) use Deno over Bun, if only because Rust is a way more safe language than Zig.
This is a non sequitur. Both Rust and Zig and any other language has the ability to end in an exception state. Whether it be kernel exception, pointer exception, or Rust's panic! - these things exist. The reason why you see so many GitHub issues about it is because that's where the development is. Deno is great. Bun is great. These two things can both be great and we don't have to choose sides. Deno has it's use case…
There are degrees to this though. A panic + unwind in Rust is clean and _safe_, thus preferable to segfaults.
Java and Go are another similar example. Only in the latter can races on multi-word data structures lead to "arbitrary memory corruption" [1]. Even in those GC languages there's degrees to memory safety.

#293No strategic roadmap is ever going to tell you: "Build a $0-revenue JavaScript runtime and one day an AI company will acquire you"
Honestly that's probably the best play. Monetizing dev tools directly is a nightmare.

But how is another company that is also VC backed and losing money providing stability for Bun? How long before we hear about “Our Amazing Journey”? On the other hand, I would rather see someone like Bun have a successful exit where the founders seem to have started out with a passion project, got funding, built something out they were excited about and then exit than yet another AI company by non technical founders…
Re: Anthropic acquires Bun
#297Bun is such a great runtime. If you haven't tried it, try it. It's got bells and whistles. This will make sure Bun is around for many, many , years to come. Thanks Anthropic. Why Bun? Easy to setup and go. bun run Bells and whistles. (SQL, Router, SPA, JSX, Bundling, Binaries, Streams, Sockets, S3) Typescript Supported. (No need to tsc, bun can transpile for you) Binary builds. (single executables for easy deployment…
> This will make sure Bun is around for many, many, years to come. Well, until the bubble bursts and Anthropic fizzles out or gets acquired themselves.

I find comments like this fascinating, because you're implicitly evaluating a counterfactual where Bun was built with Rust (or some other "interesting" language). Maybe Bun would be better if it were built in Rust. But maybe it would have been slower (either at runtime or development speed) and not gotten far enough along to be acquired by one of the hottest companies in the world. There's no way to know. Why did Ant…
Because maybe they reached out to them, and they didn't took the money, while Bun folks business model wasn't working out? Who knows? Besides, how are they going to get back the money spent on the acquisition? Many times the answer to acquisitions has nothing to do with technology.
Anthropic chose to use Bun to build their tooling.

Why didn't they just use AI to write their own Bun instead of wasting 8-9 figures on this company? Makes no sense.
They're effectively bringing on a team that's been focused on building a runtime for years. The models they could throw at the problem can't be tapped on the shoulder, and there's no guarantee they'd do a better job at building something like Bun.

I'm curious what people think of quotes like these. Obviously it makes an explicit, falsifiable prediction. That prediction is false. There are so many reasons why someone could predict that it would be false. Is it just optimistic marketing speech, or do they really believe it themselves?
