It is interesting, but there has been a bot set up, based on all of John's interviews and quotes, in which you can ask questions and chat, and it would almost be as if you were talking to John. It is the John Lennon Artificial Intelligence Project. Have a bash and tell me what it's like.
I had a go on it ages ago....Started off interesting enough but soon got boring. It's still a great idea and i am sure the AI bot will improve as time goes on.
