Quote from the CEO of Anthropic in March 2025: "I think we'll be there in three to six months where AI is writing 90% of the code and then in 12 months we may be in a world where AI is writing essentially all of the code"

Maybe he was correct in the extremely literal sense of AI producing more new lines of code than humans, because AI is no doubt very good at producing huge volumes of Stuff very quickly, but how much of that Stuff actually justifies its existence is another question entirely.

As someone who have been using Deno for the last few years, is there anything that Bun does better? Bun seems to use a different runtime (JSC) which is less tested than V8, which makes me assume it might perform worse in real-world tasks (maybe not anymore?). The last time I checked Bun's source code, it was... quite messy and spaghetti-like, plus Zig doesn't really offer many safety features, so it's not that hard t…

Why? Genuine question, sorry if it was said/implied in your original message and I missed it.

Earlier quoted context omitted.

I haven't used Deno, but I do use Bun purely as a replacement for npm. It does the hard-linking thing that seems to be increasingly common for package managers these days (i.e. it populates your local node_modules with a bunch of hard links to its systemwide cache), which makes it vastly quicker and more disk-efficient than npm for most usage. Even with a cold cache, `bun install` with a large-ish dependency graph is…

pnpm does all that on top of node. Also disables postinstall scripts by default, making the recent security incidents we've seen a non-issue.

I’m not sure why but bun still feels snappier.

Bun has completely changed my outlook on the JS ecosystem. Prior to Bun, there was little focus on performance. Now the entire space rallies around it. Congrats to Jarred and the team!

That is the most absurd thing I've heard in 20 years. Chrome literally was launched on performance, for JS and beyond.

The reality is that the insane "JS ecosystem" will rally around whatever is the latest hotness.

I’ll be honest, while I have my doubts about the match of interests and cohesion between an AI company and a JS runtime company I have to say this is the single best acquisition announcement blog post I’ve seen in 20 years or so. Very direct, very plain and detailed. They cover all the bases about the why, the how, and what to expect. I really appreciate it. Best of luck to the team and hopefully the new home will su…

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…

Reminds me of when Tron, the crypto company, bought BitTorrent.

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.

Congrats... > Long-term stability. a home and resources so people can safely bet their stack on Bun. Isn't it the opposite? Now we've tied Bun to "AI" and if the AI bubble or hype or whatever bursts or dies down it'd impact Bun. > We had over 4 years of runway to figure out monetization. We didn't have to join Anthropic. There's honestly a higher chance of Bun sticking out that runway than the current AI hype still b…

I say don't muddy the water with the public panic over "will it won't it" bubble burst predictions. The effective demand for Opus 4.5 is bottomless; the models will only get better. People will always want a code model as good as we have now, let alone better. Bun securing default status in the best coding model is a win-win-win

Opus 4.5 is not living in vacuum. It’s the most expensive of models for coders and there is Gemini 3 pro - with many discounts and deepseek 3.2 that is 50x cheaper and not much behind.
