You don't need a masters anymore than you do to read a paper in the field. I mean you can say the exact same thing about web searches. You can use logic and reason combined with some double checking to validate its output. I personally have instructions to provide references for all answers it gives so that I can double check and get a better idea about the thing im looking into. It is disturbing though how much of its output is hidden behind its learning and it can't give you a reference.
