LAWL. Do improv.... I don't think robots could be programmed to "Do improv".... that requires concepts that only humans are capable of. Like humor, Irony, timing, delivery...
This robot is impressive...but not completely amazing. Robots will never be able to produce OR play music in the same way humans do. They will forever lack that which makes us human...our self-awareness, our awareness of others and our empathy for others. A robot can play a minor chord...but do they feel the darkness of it's tone? They may nail vibrato but can they produce the real emotional power behind it?
Silly Robots and people that dream of them doing crazy things...they aren't the future...they are the past.
