There is one concern that I can't shake regarding Robotaxi: it's the difference between imitation and understanding. You can get to 99% with imitation. I don't think you can get to 100. Elon mentioned during the Shanghai interview that AI still hasn't progressed very far in terms of understanding IIRC. Take the recent riots in many of our cities. Imagine that your granddaughter and a few of her friends were taking a RT to a bar late at night and stumbled into one of these riots. A driver would know to get them the hell out of there. What is the RT algo going to do? Does it have a databank of similar situations to draw from? No. Can it rely on some rules based decision to leave? No. It won't understand the danger. What if thieves block a road to steal from motorists? Will the computer know that it's OK to run somebody over if they are pointing a gun at you? No. So what is the solution to that? Geo-fencing around bad neighborhoods? Good luck with that solution.
So my concern is that we need AI that can do more than imitate of follow rules ... it's got to understand. Maybe Apple or Google or Amazon os some Chinese company don't have our data or our chip, but maybe that isn't what gets you over the hump. Maybe the answer is in the next generation neural net?
If you think I don't understand all this stuff you are correct. I don't really understand any modern technology. I don't trust myself to evaluate whether Elon can get across the goal line ... and if so, faster than everybody else. Yes, I could just trust him. I trust him a lot. Just not enough to have 40% of my net worth riding on this working. At the current 8%, if it triples in the next few years then great, if it gets cut in half then no big deal. (You'll appreciate the logic of that better when you're retired.)
I could just as easily be talking about all the things I love about TSLA. On other boards, where people don't understand all the wonderful things happening I regularly praise TSLA and Elon. But it's important to force yourself to critically examine your assumptions. Most on this board don't seem to want to do that. Easier to put someone on ignore than to consider their argument.
