I think that has already happened and when they begin designing their own mechanisms and processors with preprogrammed circuitry.If you take all the independent robotic to human interaction tech and put it in one unit, Wow! Half the people I people I do work for would be out of jobs.
Robots that understand human language, movements, body gestures, and can talk and interact peacefully with others. Plus don't get tired or angry or play office politics either!
Put the logic based common sense of good coding on top of all that and we may all be out of work!
