Depends if I was Nikola Tesla or an uneducated factory worker. No amount of wanting it would have made it a reality though.
I've always wanted to teleport instantaneously to places instead of driving or walking. Perhaps to visit the far edges of our universe without a space suit. Or maybe restore ancient monuments or groves that are now under supermarket parking lots or churches.
It would be nice if I could "create a new character" without the flawed designs. Maybe "load a game" when I was 7 and start over with what I know now.
wanting it made it happen though, if the whole universe really came about by unguided chance as some believe, then there's probably no reason to expect an afterlife.
But otherwise, reality reflects the wishes of it's creator, whoever that may be, just like a software engineer, he is not bound by those laws and limitations of his own creation that it's users grapple with
So an afterlife would be a question of- why not? We like to preserve the information gathered by our creations, why would the creator of humanity wish to discard everything we have learned, experienced?
yes I've thought about how great that would be to start again at 7 with what I know now... but then again.. just to play devils advocate...that means a 7 year old with a lot of worry! and so much that was new and exciting to discover the first time would be a bore
