In this case, as a photographer, I think the answer is YES, for most of people a smartphone is enough, absolutely it will not replace a EVIL camera with FF sensor for the amateur photographer but this is only a small fraction of the market.
For the future I see the "pro cameras" that will use larger sensore (larger than FF), more machine learning and connected features etc... but those cameras will be only a small fraction of the market, 80/85% will be cameras inside of the smartphone with a lot, a lot of machine learning on the photos, less user interaction of more computational photography.
