>>11626620>"Scientifically"I like how you just felt the need to throw that word in there to make this question the most loosely scientific discussion and not a philosophical one, because what you're actually asking is philosophical.
Science, by and large, does not have a "purpose" beyond what we arbitrarily ascribe to it. In a broad sense, it's just another mechanism by which we make ourselves better at surviving.
The scientific method is just an extension of generalized reasoning ability, and reason is a faculty that we developed as a species because it contributes to the way we compete, ecologically, with other species, the environment, and now basically with ourselves.
All of the things you mentioned securing a future for have nothing to do with scientific discovery, they're just the current iterations to solutions for human problems, and aren't in any way meaningful to it.
