  • I’ve thought about this too but I’m not sure this would work. First you could hack the firmware of a cryptographically signed camera. I already read something about a camera like this that was hacked and the private key leaked. You could have an individual key for each camera and then revoke it maybe.

    But you could also photograph a monitor or something like that, like a specifically altered camera lens.

    Ultimately you’d probably need something like quantum entangled photon encoding to prove that the photons captured by the sensor were real photons and not fake photons. Like capturing a light field or capturing a spectrum of photons. Not sure if that is even remotely possible but it sounds cool haha.




  • Yeah it’s not a solution to everything. I imagine the standard “super light” robo taxi as a two seater with the seats facing each other. Without a driver seat you can redesign individual transport to be narrower which improves aerodynamics.

    But yeah for families or cargo transport you still need larger vehicles. Or take two. And I also imagine this to be more of a “gap filler” besides public transport or bicycles. It would really require a pretty big redesign of how we live and work to reduce our energy and resource usage to zero.



  • The problem is we can’t keep the same resources waste up. Lower range and smaller cars is what is needed. The perfect car of the future would be a one-seater that is as small and light as a electric velomobile (~70kg). Build a few millions of them and replace all cars in a city with those. Ideally self driving and as a robo-taxi, but even without the self driving this would be good. Of course cars isn’t really that high on the list for climate change.

    But as a civilization we are simply not an intelligent species.
