I mean you should get lost in knowing nothing.
When I think about life in general, and us human beings, I like to believe than in the long term (really long term, I really cannot put a number to it) one of our greater goals could be to gather every knowledge there is in the universe, I don't know if that is possible for several reasons like how to see past the event horizon on a black hole... but I like to think in the future we will achieve great things that today seem like impossible.
Absolutely, man will never stop trying to evolve and man should never stop.
Science will surely make a lot of new discoveries, but how can you you get to the end of a bottomless hole by digging it? That’s one of the mistakes I feel science makes
