Assuming that scientists are the smartest of us all, their spirituality or rather lack of it, can point us to the character of future society. I'm almost certain that in future people will make kids in hospitals or labs by gene manipulation, rather than risking sick or mediocre child made natural way. In future everybody will be smart, healthy and beautiful.
So, when all society is smart or super smart like today's best scientists, will society become more atheistic?
Will it bring the end of all religions?
There is more atheists among scientist than other occupations or general public.
It means that there is 10 times more atheists amongst scientists than in general public. This is huge difference.
Interestingly, the older one gets the less spiritual one becomes. At least as a scientist.
