  • I think it is a lot more of a continuous spectrum than the binary classification that you’ve characterized it as. I also don’t see it as “greed” per se, more as seeking opportunities/escaping poverty.

    It is also important to recognize that “cultural/wanderlust immigrants” are likely vastly more privileged than the “economic immigrants”. Most people in the global south do not have the resources to emigrate just to experience other cultures unless they are very lucky. It’s also not easy to acquire work or immigrant visas in most countries as a person from Africa/Asia etc. While it may be possible for citizens of the EU/US/Canada etc to move between countries easily with their strong passports, it’s simply not possible for the rest of the world. Immigrant blue collar workers are often either refugees, or have family in the countries they immigrate to willing to sponsor them. White collar workers either enter as students, or have intentionally acquired skills that will make it possible for them to get a job/visa.

    I do agree though that “economic immigrants” are often more wedded to their own values, though that is not always the case, but that doesn’t necessarily mean they’re right-wing. It doesn’t completely explain why their children are conservative either, given that they have to necessarily integrate a lot more with their host country’s culture. The “pulling up the ladder” phenomenon is very frustrating though, and I see it sometimes as a result of the precarious position that these people hold in their host country. They’ve likely spent a long arduous time and lot of resources immigrating, and likely will be the first ones who will be targeted by unfavorable immigration policies, so they don’t want anyone to “rock the boat” lest they lose the life they’ve built for themselves. I’ve seen this shift in mentality quite a few times, and it is very unfortunate.

    One thing about integration though, it really is a two way street. Immigrants very often don’t make the effort to integrate, but on the other hand discrimination against certain races and cultures make it much harder for them to as well. It’s a bit of a vicious cycle in that sense.




  • Not a fan of Musk at all, but Lidar is quite expensive. A 64 line lidar with 100m+ range was about 30k+ a few years ago (not sure how prices have changed now). The long range lidar on the top of the Waymo car is probably even higher resolution than this. It’s likely that the sensor suite + compute platform on the waymo car costs way more than the actual Jaguar base vehicle itself, though waymo manufactures it’s own lidars. I think it would have been impossible to keep the costs of Teslas within the general public’s reach if they had done that. Of course, deploying a self driving/L2+ solution without this sensor fidelity is also questionable.

    I agree that perception models will not be able deal with this well for a while. They are just not good enough at estimating depth information. That being said, a few other companies also attempted “vision-only” solutions. TuSimple (the autonomous trucking company) argued at some point that lidar didn’t offer enough range for their solution since semi trucks need a lot more time to slow down/react to events ahead because of their massive inertia.
