  • The money required to double the bitcoin hash rate and maintain double is immense. It’s specialized hardware that would need to be manufactured (lead time while network continues to grow, plus who even has the capacity to do that other than TSMC or Samsung) and the network would see it coming and have a chance to do something about it.

    It was a risk when it was smaller, but the ability to pull an attack off like that now and maintain the attack isn’t practically in the realm of possibilities. (Edit and that’s not even getting into where they’d get the power to power the network which is estimated at 173Twh a year and the need to keep expanding that power to maintain the attack in adversarial conditions.)

    Attacking the network in other ways via corrupt laws with multi government cooperation would be far easier.








  • So the headline is pretty inaccurate.

    There will be a person in the passenger seat. They aren’t a safety driver, or driver at all. They’ve been operating with an actual safety driver for around a year now for employees only.

    We don’t really know what they’ll do, but I highly doubt it’s jump for the wheel if it’s about to do something. I think it’s going to be more of a, the car decides it can’t do anything and is just sitting there incorrectly and they won’t have to dispatch someone to fix it like Waymo does. This could be a legitimate saftey issue if the car is just stuck on the road.

    Once they’re happy it’s not getting in situations like that they’ll remove the person and dispatch people as needed.

    But we won’t know for a few more days when we get reports of what they’re doing while the first people test it.




  • I’ve had recent problems with FedEx like this as well. Like 3 of the past 4 deliveries it says it’s going to deliver maybe a day early, then just fucking sits in the depo in the city ALL DAY while still saying it’s going to be delivered today, until it’s the end of the day and it switches to tomorrow.





  • AEB braking was originally designed to not prevent a crash, but to slow the car when a unavoidable crash was detected.

    It’s since gotten better and can also prevent crashes now, but slowing the speed of the crash was the original important piece. It’s a lot easier to predict an unavoidable crash, than to detect a potential crash and stop in time.

    Insurance companies offer a discount for having any type of AEB as even just slowing will reduce damages and their cost out of pocket.

    Not all AEB systems are created equal though.

    Maybe disengaging AP if an unavoidable crash is detected triggers the AEB system? Like maybe for AEB to take over which should always be running, AP has to be off?
