We're moving into a future where we begin to manipulate genes and technology to transform humans themselves. Interesting times.
The mouse experiment is fascinating because one of the ideas proposed was that it wasn't physical crowding but over stimulation socially which was producing the results. The big question, which is unanswered, is how much about human behaviour can we learn from studying mice and rats.
I guess the JW utopia to me is always the one of thought crime and total loss of individuality and creative expression otherwise. My idea of hell really. Even growing up inside, the idea of a panda was nice but listening to kingdom melodies every day really didn't appeal. Nor did having to live with the people in my congregation for all of eternity (with a couple of exceptions). And no books but WBTS ones was really not going to make me want to go to paradise. Liberating moment to realise that you don't mind not having that fixation on getting through Armageddon to the 'promised land'.
