Honestly, these arguments have been heard since "forever" and of course history is littered with a lot more people who declare something would be impossible to see it happen than it is littered with people who died expecting something many people thought would happen soon. Or, there are both types to be sure, but a lot more of the former. So how do I take your money with a bet? Of course, I will win the bet easily because people plan to "cheat" because that's what you do to make a commercial service. We have your robots that will go to the restaurant and get your order and bring them to you. We do many thousands of deliveries for paying customers in several towns every day. No, we don't take your spoken order, because that's stupid, you order online like any 21st century human would. I don't think Burger King is a partner but they could be. This is not something from the future. It's been running for over a year. So I guess that would not be a very fair bet, would it? But happy to take other bets. Arguments about how long things took to develop are nice as analogies but don't actually inform. Real developers pay no attention to the "levels" like "level 4" but they do indeed have no intention of operating outside a constrained zone because they don't need to to be useful. They certainly don't need it to be always connected for any safety function -- they are not crazy. How much of your money can I have?
