Vacuum cleaner -> sell appliances -> sell electric motors
But there was a clear advantage in quality of life for a lot of people too.
Automobile -> part of industrialization of transport -> faster transport, faster world
Arguably also a big increase in quality of life but it didn't scale that well and has also reduced the quality of life. If all that money had gone into public transport then that would likely have been a lot better.
Airplanes -> yes, definitely, but they were also clearly seen as an advantage in war, in fact that was always a major driver behind inventions.
Steam engine -> the mother of all prime movers and the beginnings of the fossil fuel debacle (coal).
Definitely a quality of life change but also the cause of the bigger problems we are suffering from today.
The 'coffin corner' (one of my hobby horses) is a real danger, we have, as a society, achieved a certain velocity, if we slow down too much we will crash, if we speed up the plane will come apart. Managing these transitions is extremely delicate work and it does not look as though 'delicate' is in the vocabulary of a lot of people in the driving seats.
