The world's first AI lawyer was just hired at a law firm

Lawyers can get a bad reputation for being slimy and conniving, but ROSS has neither of those qualities. Ask ROSS to look up an obscure court ruling from 13 years ago, and ROSS will not only search for the case in an instant -- without contest or complaint -- but it will offer opinions in plain language about the old ruling's relevance to the case at hand. Just about the only thing it can't do is fetch coffee. Not that anyone should blame it, seeing as ROSS is a piece of artificial intelligence software. It uses the supercomputing power of IBM Watson to comb through huge batches of data and, over time, learn how to best serve its users.
