Technology generally tends to improve lives everywhere and for everyone.
Yes, there are almost always negative side effects, but we tend to find a lot more good use for technology than not.
The first man made fire could hurt another person, but was probably useful for a few more things.
Self driving cars that only drive the rich around is silly. That means it will have no market penetration. No market penetration means no profit.
And then why are people scared of self driving tech? I mean, if you dont want to use the technology, just dont.
Its like complaining that facebook is ruining everyones life, and then continuing to use facebook.
Again, the tech wont magically appear and take over all cars instantly. It takes about 10 years to replace all the cars on the roads. So even if they started making every car roll off the assembly line today be 100% self driving, you have 10 years where you can live in bliss. But the reality is, if there is a market for people who dont want self driving, there will be none self driving cars. It will take a very long time before the tech gets into even 50% of new cars as an option, never mind standard.
Self driving cars, like any other major tech in the past will have good stuff and bad stuff.
Truck drivers will lose jobs, but deliveries may happen quicker and cheaper.
Your not complaining that the incandescent light bulb put candle makers out of business now, and you wont complain that truck drivers arnt a thing in 20 years time. We will move on.
