True. Computers are babies and will continue to grow. However, there are two types of work that exists.
1) High complexity problems
2) Low complexity problems.
I argue that #1 is far from automation because we don't fully understand #1. #1 consist of the first paragraph you cited in bold. #2 is low complexity problem and they are prone to machine intelligence and automation. Throughout history we have seen #2 be taken over by robots. Examples of #2 are cashiers with self checkout, rental associates with redbox to rent movies, librarians with wikipedia-like database to look for information, accountant with turbo tax, and so forth. The list can go on. People working in these industry will see their labor allocation to lower complexity be dissolve and they will be reallocated to higher complexity problems assignments. Some will lose their jobs but some will find their work having more meaning.
What this means to us as a society is we need to focus on #1. #1 require higher levels of education, and skills in focus, concentration, critical thinking, meditation/reflection, and ultimately problem solving. To me, problem solving is a creative process in the mind wrapped around a well defined engineering problem in the physical world.
What this mean for entrepreneurs is we have to think about stuff that don't even exists...we have to be at the frontier of science and define how the future will look like. I believe the purpose of all that we do is to progress the human race and while doing these things be grounded in virtue and morality and continue to battle our desires for vices.
