Artificial intelligence is doing so much of tedious work that we would otherwise hate to do!! But here i have a second thought on how well the filtering system would be?? How it could differentiate trolling or real life advancement but harsh on wording suggestions?? Do the authors get to fine tune the detail for the filtering?? Anyway indeed this will bring out a much more "positive" world but sometime its the harsh critical comments that help us grow, but of course getting rid if trolls are the best thing it could do!!
