While it is somewhat true that building all these robots to help us and replace some jobs might eventually bring us to a point where they replace most of us

and there will be no more jobs for humans themselves, I think that the good will outweigh the bad.

Humankind is healthier than ever, thanks to all the technology and robots. Dangerous jobs can be done with robots and in most cases robots are more accurate and make less mistakes.

Technology gets better and better all the time, and while it may make some of us lose our jobs, it also brings new ones.
