Like others have suggested, I'm not terribly trusting of this new 'paradise'. I guess we're all too cynical or maybe sensible. So, we question how this new world would be run. Would we still be fallible humans? That in itself brings in a whole host of problems. In which case, can we truly envisage being a different entity? I think it sounds like too much risk for most of us.
Interestingly though- I think that's why many of us have little faith in 'recovery' in this world. Our 'perfect' or even just vaguely tolerable world may not actually feel achievable. We recognise that it's fantasy. The perfect job, the perfect partner, the perfect body, perfect health and wealth. If we can't even envisage a perfect imaginary world with those things, how on earth would we get them here? Where there are limitations everywhere?
So- N seems safer. But- having said that, this 'perfect' world presumably offers assisted suicide and, no one grieves for you for doing it. So- maybe- under those circumstances, it would be worth checking it out. I'm absolutely up for seeing a flying dolphin and a singing whale. Without further detail and reassurances though- I'd reckon it was a scam and go for the N.
