Will singularity happen ??
It probably happened already. I think we're in some kind of ancestor simulation. It's just too much of a coincidence to be alive at such a pivotal point in history.
I mean, when I die of old age (presumably around 2055-2065), that's pretty much the exact point when I can foresee this 'Singularity' taking off. A decade or two after Kurzweil's prediction date of 2045. Presumably that's when the 'game' ends, I get revived (alongside thorough techniques to reduce the psychological shock), and discover it's actually centuries or millennia hence. I was in some kind of simulation/game all along, created by the hyper-advanced AI of the far future. Perhaps the game was even created by myself or some combination of me and the AI.
Then I get to 'play' again – because I'm immortal and in digital form – so I can be downloaded into a new body (with previous memories erased), to try a new 'life' all over again –Quantum Leap-style. Perhaps this could happen billions of times, until I've experienced literally every life there ever was on Earth, back in the distant past. I only become aware of the 'real' date and the 'real' reality when a death happens, at the end of each 'life', and my memories are restored when I temporarily pop back into the simulation room.
Then again... maybe the world I see around me is base reality, and it's just a staggering coincidence that I live during what feels like the cusp of a new era in Earth's history.
Either way, the mid-21st century will be profoundly exciting.
