  • Apple doesn’t want it to be VR. They want people to buy this expensive VR headset and wear it all day, but you can’t wear it in public because of how silly it looks, and you can’t carry it around everywhere because it doesn’t fit in your pocket and you can’t just toss it in a bag without damaging it, and you can’t even just wear it around your house unless you’re moving from outlet to outlet. The Vision Pro is an impossible cross between Facebook’s Quest Pro and Smart Glasses products. The technology to make a successful product out of it doesn’t exist yet.

    There are ways to use the Vision Pro as a regular VR headset, but then you’re paying for things you’re not using.




  • The Index by itself is 500 dollars, not 1k.

    LCD screen was a feature of the Index over the OLED screen in the Vive. On the Vive, the OLED has a visible pattern and some of the image is lost because there aren’t an even number of red green and blue subpixels (similar to PSVR2). The Beyond is screen is micro OLED with a more regular subpixel pattern.

    PSVR might be the only headset available with these features for cheaper, but not much cheaper, and it doesn’t have the headphones.



  • Would it though? It’s just vans on tracks instead of roads.

    It’s not going to be more energy efficient with individually powered cabs. It’s not going to be more convenient unless your origin and destination are near a station. It’s not going to be more time efficient because of the extra distance getting to and from tracks and because you aren’t going to drive highway speeds in tiny self-balancing cars on old rails, especially when passing cars going the opposite direction. It’s not going to be more cost efficient because it’s more total moving parts requiring maintenance per person per trip.

    It sounds like they are solving the problem of turning around only for terminal stations. This might make sense for trains that carry many people, but if you’re making cars on tracks there is no good solution. If you need to spend money on a system that turns the cabs around, then you either spend more money installing those systems at most stations or you spend money maintaining cabs that are driving around empty. Either way, cars on roads are cheaper.

    They say it’s good for people who don’t want to wait for public transit, but they don’t say how this solves that problem. With public transit, you know when the train will be there. With this, unless they have a way for the cabs to wait at the station without blocking other cabs going the same direction, you have to wait for a cab to come and you can’t time your trip to the station around when the cab will be there. Maybe they have one? It would be a disaster if you wanted to get on from near the middle and needed to wait for either a cab that has already been vacated to come or for a cab to come all the way from the start of the track.




  • Are people in this article really suggesting that the 100% emoji is racist? You can never get a perfect score or agree with anything again because a small number of people have used that number to mean something else and now somebody will interpret it as a hate crime.

    At first they were arguing that somebody writing “shit” in an exaggerated way, and the occurrence of two other numbers and an elongated asterisk were Nazi symbols, and they could be, but the only evidence is that somebody said they thought it was too many coincidences. I don’t know enough about the circumstances to say it is or isn’t intended that way. Management apparently thinks it isn’t. But saying multiple people reacting “100%” to a message they agree with means they’re all using the number 100 as a sign of white supremacist solidarity is ridiculous. What else are they going to do? React with the “OK” hand? No, the ADL also decided that one is racist. React with thumbs up? No, younger people have decided that one is rude.
