Every single technological advancement relieves someone of work. This allows people to put their money towards things that they would rather put money towards, creating more jobs there. This makes the world a better place.
It may also create other jobs etc., but clearly the wealth transfer is one part of the effect. I think that as a result it is important to pursue social policies to mitigate the disruption experienced by displaced workers, and to spread the benefit of the technology to a larger fraction of society.
