Self-driving just suffers from good old software project time underestimation and overpromising executives.
It's quite possible to outdo a human at keeping rolling boxes from hitting each other and the unpredictable human particles buzzing around them. (Mainly because humans suck at paying attention and don't have millisecond response times.)
It's also quite possible to put people on the moon, but budgetary appetites are always the limiting factor.
So self-driving can still die if the difficulty exceeds the money and patience of the people footing the billions. Shareholders are free to say "why are we still paying for this when we were promised success 5 years ago?" and demand the plug be pulled. I hope they don't, but I also hoped NASA would get a higher budget.
- Invictus0 3y agoHumans have 0.2s response time. It’s astoundingly good. I’m in robotics and our pipeline time is nowhere remotely near 0.2s.
- marcosdumay 3y agoWell, not for anything complex. We can't even compensate some unexpected steering in 0.2s, while robots can do that in some µs.
- gary_0 3y agoIf you're measuring a human in front a screen with their finger on a button, and the human is young, healthy, and fully alert, then you get 0.2s. Some electronic safety systems[0] can indeed physically respond in µs. Some robotics might have lag due to mechanical slack or software/processing limitations, but that can always be improved. Whereas humans are never going to do better than 0.2s and will usually do much worse, especially if they have to turn their head, focus their eyes, and manipulate physical controls.

- gary_0 3y agoI used to develop for CNC systems, and those responded to sensor trips within microseconds. The computers involved were realtime systems. If everything wasn't that fast, the machines would have demolished themselves. A human pulling a lever would have been 500,000x too slow.
- dghlsakjg 3y agoRobots beat humans at things like determining if a circuit has been completed (sensor trips), and following a predefined set of directions. Humans are far better at complex things like reacting appropriately to an unanticipated input (someone yelling stop, or honking a horn)
