With more and more human activities being replaced by machines,
in the future having a Master's will become a de-facto standard for a professional, just like having a Bachelor's is today.
The only significant weakness that machines have and will have in a foreseeable future is their inability to act effectively in an even slightly changed environment.
Machines are also unable to apply themselves to any new kind of data without a human programming a reader/feature extractor.
Future professionals will be intermediates between the real world and a machine. A role similar to today's laboratory scientist.
