  • Like I said, the argument is that if AI vision is actually solved, at that point it’s like walking with perfect vision and a blind cane.

    LIDAR’s true strength isn’t even useful for driving at speed. LIDAR is super precise - useful for parking perhaps, but when driving at 50km/h or faster, does it really matter if the object in front is 30.34m ahead or 30.38m?

    Also, the main problem with LIDAR is that it really doesn’t see any more than cameras do. It uses light, or near-visible light, so it basically gets blocked by the same things that a camera gets blocked by. When heavy fog easily fucks up both cameras and LIDAR at the same time, that’s not really redundancy.

    I’d like to see redundancy provided by multiple systems that work differently. Advanced high resolution radar, thermal vision, etc. But it still requires vision and AI 100%: the ability to identify what an object is and its likely actions, not simply measure its size and distance.


  • People are hopping on LIDAR as the one stop solution to self driving without understanding what it is. Probably for no reason other than the fact that Musk doesn’t like it, therefore the complete opposite must be true!

    LIDAR just makes the “easy” problem of self driving more robust. i.e. “Don’t crash into object”

    It does nothing for the “hard” problem of self driving. “What does that road construction worker mean when they are waving their hand that way?” or “Is that pedestrian waiting to cross the road or just standing there waiting?”

    LIDAR does absolutely fuckall to solve those types of problems. It will basically say, very precisely, “there is a 1.86m tall object 8.54m in front of you, don’t crash into it.” And “there is a 1.71m tall object standing 4.55m to your right, don’t crash into it.”

    To solve self driving, vision AI MUST be solved.

    Tesla is betting that they will solve the vision problem, and by the time that is solved LIDAR will be redundant. Like a person with perfect vision walking with a blind cane. Yes, the cane can serve as a backup, but… why bother at that point? Although right now Tesla is basically like a very nearsighted person walking without glasses or a cane.

    Waymo is using LIDAR so it avoids the catastrophic, headline-making screwups that Tesla does. They just kinda… get stuck, call a human operator to assist, and still use individual human operators to fix the problem. Kinda like the blind man with the cane, who has to call his friend to help out constantly. He might be fine on well travelled routes he’s memorized.

    Both are not at the point where they are truly self driving without human oversight. And again, vision AI is the key, not LIDAR. LIDAR is just the trumped up version of the anti-collision radar every car has today.



  • Nope. If your other finger is still resting on the mouse, it fucks up and can’t tell the difference between left and right click. It’s a 50/50 gamble unless you lift your fingers off beforehand.

    Yes, I did use the mouse before, and I was wondering why the fuck the thing kept right clicking when I left clicked and left clicking when I right clicked. Only after googling did it reveal that it misinterprets shit if both fingers are resting on the mouse.

    What kind of fucking mouse requires googling to click?

  • You’ll be perpetually behind the times. People tend to get set in their ways even by their 30s. You’ll constantly lag behind the trends, language, and tastes of the younger generation…

    If you were the first to be immortal, you may not have the best version of immortality and it may render you incompatible with better, future types of immortality. Like magical regeneration that prevents you from getting a personality upload to a cyberbrain that is a million times faster and smarter than the squishy biological brain.
