This announcement made me check in on the arbitrary code execution bug I reported that the Bun Claude bot created a PR for about 3 weeks ago: https://github.com/oven-sh/bun/pull/24578 So far, someone from the bun team has left a bunch of comments like > Poor quality code ...and all the tests still seem to be failing. I looked through the code that the bot had generated and to me (who to be fair is not familiar with t…

So you pushed a PR that breaks a bunch of tests, added a 5 layer nested if branch block that mixes concerns all over the place, then ignored the reviewer for three weeks, and you’re surprised they didn’t approve it?

No strategic roadmap is ever going to tell you: "Build a $0-revenue JavaScript runtime and one day an AI company will acquire you"

Well, that was the playbook in the 1999-2001 dotcom days.

Which is probably why no one's going to recommend it these days

...but hey, things are different during a bubble.

If I had the cash, I could sell dollar bills for 50 cents and do a $7b run rate :)

Surely you understand the bet Anthropic is making, and why it's a bit different than selling dollars at a discount

Because discounted dollar bills are still a tangible asset, but churning language models are intangible?

Probably about 95% of mine now. Much better than I could for the most part.

Weird, AI writes terrible code for me that would never pass a code review. I guess people have different standards for good code.

I suspect you do not know how to use AI for writing code. No offence intended - it is a journey for everyone.

You have to be setup with the right agentic coding tool, agent rules, agent tools (MCP servers), dynamic context acquisition and workflow (working with the agent operate from a plan rather than simple prompting and hoping for the best).

But if you're lazy, don't put the effort in to understand what you're working with and how to approach it with an engineering mindset - you'll be be left on the outside complaining and telling people how it's all hype.

The difference is that Tron is a scam and BitTorrent Inc was nothing special either.

Match made in heaven considering BitTorrent Inc bundles crypto miners and other malware with μTorrent.

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…

Ditto, and I got to know Bun via HN. It seemed intriguing, but also "why another JS runtime" etc.

If Bun embraces the sweet spot around edge computing, modern JS/TS and AI services, I think their future ahead looks bright.

Bun seems more alive than Deno, FWIW.

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"

AI writes about 90% of my code.

What languages and frameworks? What is the domain space you're operating in? I use Cursor to help with some tasks, but mainly only use the autocomplete. It's great; no complaints. I just don't ever see being able to turn over anywhere close to 90% with the stuff we work on.

If that was genuinely happening here - Anthropic were selling inference for less than the power and data center costs needed to serve those tokens - it would indeed be a very bad sign for their health. I don't think they're doing that. Estimates I've seen have their inference margin at ~60% - there's one from Morgan Stanley in this article, for example: https://www.businessinsider.com/amazon-anthropic-billions-cl...

The leaders of Anthropic, OpenAI and DeepMind all hope to create models that are much more powerful than the ones they have now. A large portion of the many tens of billions of dollars they have at their disposal (OpenAI alone raised 40 billion in April) is probably going toward this ambition—basically a huge science experiment. For example, when an AI lab offers an individual researcher a $250 million pay package, i…

Not really. If the technology stalls where it is, AI still have a sizable chunk of the dollars previously paid to coders, transcribers, translators and the like.

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…

I always figured Bun was the "enterprise software" choice, where you'd want to use Bun tools and libraries for everything and not need to bring in much from the broader NPM library ecosystem. Deno seems like the better replacement for Node, but it'd still be at risk of NPM supply chain attacks which seems to be the greater concern for companies these days.

If you want to download open source libraries to be used in your Bun project then they will come from npm, at least by default. [1].

So it seems odd to say that Bun is less dependent on the npm library ecosystem.
