Delicious meta thought from this morning: The table pounding from the AI-skeptical software engineers, shouting "they can't build proper, scalable, performant programs!", sounds especially thin when you consider that right now nearly everyone is looking for where this is going and no one knows yet. Building something "proper" and "scalable" and "performant" before you have PMF is a tricky thing to pull off (there's exceptions, of course, where PMF comes from being one of the three) and now it seems like most companies are looking for PMF every 3 months.

People want Jarvis. Or an AI version of Alfred. They want Jarvis/Alfred to handle all mundane details in their life, and we are nearing that. Right now, they have localized chat and decent agents that still struggle with basics but are on the trajectory.

(A bit like Shopify's phase transitions in their GSD system). I have a handful of tasks that should be checked in a review. It used to be normal practice that any list in a UI needs a title. Eg "List" or "Untitled" etc. But this was always a drag, right? Naming a list just to have a group of things is extra work. But without a name it's hard to scan and find and all lists look the same. Now AI can generate titles for anything. Li… Related

On Golden Gate, you can chat to the built-in foundation model directly with `fm chat`. You can also do things like pipeline it into scripts. E.g., in the second screenshot here it's reading and summarizing a @sixcolors article. The model's context window is quite small, so I had to write a script that chunked the text, so it's sort of serially summarized. Still, it’s nice to have fully-local access to this model in this way. Related

I don't think anyone seriously advocates "let anyone post whatever", but rather the question is (as so often) who is responsible. If the author themselves say they don't fully understand what some AI has proved, and it's wrong, then whose fault is that? Does the arXiv get the blame for allowing the content? Fwiw, I think that in this case AI solves more problems than it creates. If a paper is plausibly correct and lives up to the standards of the field, and the author has done their best, even if written by AI, why not just post it in a 'mostly AI' subsector (maybe just an extra flag for each… Quoting @Quasilocal To everyone now claiming arXiv should let everyone freely post whatever: you already have venues like that. The fact arXiv is different is literally the only value it has over those others. Related

Listen if your model of what has happened is that the EAs have launched a coup I think you have very bad judgement. Here is what actually happened: a very large number of people have slowly grown aware of the potential AI has to radically transform human society. Most people who contemplate this are uncomfortable with this—because they do not like change, because they do not like ceding agency and control to something they do not understand, because they distrust Silicon Valley, because they fear the apocalypse, because they fear the dystopian-lite future many AI futurists advocate as a the “… Related

If anyone wants a nice side project... The fast number parsing fast_float (part of GCC, and other important systems like MySQL) is not always exact when dealing with 16-bit float parsing (specifically float16_t). That is, some number strings can lie in between two numbers and the rounding is wrong. In fact, nobody has done a proper analysis of the implementation to insure that it is correct. Yeah. I could ask my AI, but it is still work, especially because I do not trust anyone, not even an AI, to get it correct the first time around. Contributions invited. github.com

General partner at Benchmark Capital for over two decades; was the lead analyst on Amazon's IPO before moving into venture capital. Writes Above the Crowd on tech and marketplace economics.
Sound like many employees at Anthropic share Jacob's POV, as many posted yesterday that (1) they agree, and (2) said that many more inside the company do also. It would be useful to name this "belief system" so that we can talk about it in a reasonable way. I suspect "doomer" seems derogatory, and "accelerationist" has others uses. If there a word we can use so that we can have proper discourse? I'm very serious. I think it would be helpful. Anthropic Related

many people reported astra draining quota way too fast i ran an empirical study to quantify this for us. now here's some hard data - 1. in terms of "how many $ of tokens do you get from 1% of weekly quota", astra and sol aren't meaningfully different, so OpenAI is not "cheating" or anything they both give around $13-15 per 1% of weekly quota on the $200 plan (btw this also shows you the month value of the subscription is ~$6000) 2. however, astra works much faster than sol while being way more expensive in terms of pricing. these two factors compound into a 2x faster drain on your quota the s… OpenAI Related

Lots of risk with AI. I worry a lot about cybersecurity for example. However, “extinction risk” — literally 100% of humans die — is not remotely one of them. Quoting @DavidSacks “I think they're having AI psychosis… I'm not sure they're dispassionate critics, observers of what's happening.” Related

I've been surprised to find that sometime in past six months or year, ChatGPT has generally started returning better results than Google for me. OpenAI probably has fewer employees than Google Search alone, and what fraction of OAI works on search? On the order of 1%?
