Thanks to Alex Holcombe  I found this movie and had the feeling I understood something. This seems a real breakthrough to me for machine learning,  very convincing demos. 30 or 40 years ago I had – compared to now – lots of free time on my hand; I built organs and synthesizers and failed at learning #guitar. With that time now I’d play with this, looks to me as if it wouldn’t be too difficult to program.
