What do you think life will be like after robots take every job we do now?
Life simply won't be.
By the time we have the technology to give the necessary skills to robots to do all our jobs, some person or group is going to maliciously code a robot to self reproduce, consume all resources and destroy all life on earth.
The television show Stargate has it right my friends.

Several companies have been working on your idea for years already. Congrats!
