Neural network fads come around every 25 years (1960s - killed on purpose by Minsky by his book Perceptions. Minsky wanted everybody to work on his type of AI, symbolic AI which went nowhere. Late 1980's. 2010s.) They usually die out, leaving no trace behind. Maybe this time it's different, imho because of Google translate. Most neural networks don't actually earn any money. But in general they make super slick demos, that's for sure .
