Jeremy Howard[0] gave a TED talk[1] in which he predicted that this would be a short-term trend, where labelling data for AI will be an easy way to get a job for a few years. He predicts that this will drop off as enough labelled data is provided. I think this fails to consider that our expectations of AI will increase along with our ability to manipulate increasingly large amounts of data, so we will begin labelling increasingly complex data.
