  • Yeah, but they never really systematically subsidised fares as such, except for some one-off bonuses to attract divers and stuff like that, in the sense that they didn’t systematically pay drivers more than people were paying per ride. They subsidised it in the sense that the cut they took didn’t cover their development costs, servers, marketing, etc. But those costs don’t increase linearly per customer and they also plateau as the software stack matures, so there’s a path to just raising prices and getting to profit, and each additional customer brought them closer to profit even while the subsidies existed.

    OpenAI and Anthropic are paying something like 10x the amount for inference as they get from subscriptions, let alone free usage and training costs. So each new customer is taking them further from being profitable. And if they jacked up the prices 10x, so that the basic subscriptions were a few hundred and the pro ones a few thousand a month, they would still be in the position that Uber was when they were doing the subsidies for their infrastructure. I think it’s fairly obvious that they wouldn’t be acquiring customers very quickly at those prices.









  • I actually liked a lot of the food I had when I lived in the UK. Not necessarily all the cuisine as such (although plenty of it is fine), but I found in general that supermarkets had really good quality produce and ingredients for very decent prices, and I love cheddar and various other British staples. An English breakfast is great too, and I know this picture isn’t representative.

    But Australia and NZ have really perfected pies and sausage rolls, and they’re far more of an everyday thing. You can get pretty decent ones basically anywhere. I moved to the UK after a couple years in France, where the food was of course great, but I was really looking forward to being able to finally get a good sausage roll. So you can imagine my disappointment when I couldn’t.

    i remember there was a diode and transistor that were literally completely seperated from the traces of the rest of the chip, and yet they were functional pieces and the chip wouldnt work if you removed them.

    If that was true they would be getting the Nobel in physics for discovering some incredible new quantum phenomena, it would be front-page news everywhere. I highly doubt it’s true.

    Frustratingly, that article you linked doesn’t actually link to the paper. But it is in Nature Communications. That’s a respectable journal but not that prestigious, and it publishes a lot of over hyped stuff. Not that any journal doesn’t. But if they had really found new physics with AI chip design that would go to Science, Nature, or maybe PRL.

    Edit: ah, I found it.

    Chip design isn’t at all my specialty so take my opinion about this with a grain of salt. But I think it’s notable that

    Prior works in nanophotonics have demonstrated the class of inverse methods for specific dielectric-based passive structures through gradient based optimizations such as adjoint method

    So, there are already known algorithmic approaches to solving for these. I think it’s also notable that these are for signal transformation and antennae, relatively simple operations.

    This seems like a vaguely useful result but I don’t expect it’ll be breaking any new ground any time soon.
