Well when the cars were invented did people start living in a dystopia where the car moguls owned mobility itself or did people just got around much faster and had better lives in general.
It was mixed. People got around faster and stuff was cheaper. On the other hand, we got fat and dependent on cars, which is particularly bad for the poor (since cars are inherently expensive), and for kids' independence. That's why you're seeing many metro areas starting to prioritize walking, biking, and transit.
On balance the development of cars was good, obviously, but let's not kid ourselves, the downsides were significant.
I'm not sure if it is an established fact that people got fat because cars came along (before cars there were carriages). I'd rather bet that diet is the culprit.
If we look at agriculture mechanization, we went from 80% of the population to 5% to feed everyone. While this is good for everyone, I don't think farmers are living some sort of utopia.
Rather most of them are indebted for decades to pay for their complex equipment.
I believe the introduction of robot will follow a similar pattern, some industry will see their number of employee reduced drastically but they won't necessarily increase their margin. The customer will likely win.
The thing is that people who were employed in farms moved to factory. Nowadays I don't know where people who lost their job to robots will move.
