For me the guitar is like the keyboard I am writing on right now. It will never be replaced, because that is how I input music into the world. I could not program that, I was doing tracker music as a teenager, and all of the songs sounded weird, because the timing, and so on is not right. And now when I transcribe demos, and put them into a DAW, there seem to be the milliseconds off, that are not quite right. I still play the piano parts live, because we don't have the technology right now to make it sound better than a human, and even if we had, it would not be my music, but what an AI performed.
