My original point was that machine learning is not something that the average person can apply in his or her own business yet. Yes, big tech companies use it to improve their operations, but a small business owner can't define what would even be an applicable ML problem for their business yet. Millions of small businesses have websites, and even their own custom software, yet ML is still out of reach for many of these business. This is where I think a huge impact can, but has yet, to be made.
