As I was sitting in class today, and began casually wondering about whether or not humans will evolve further, and assuming they do, what could be predicted about the future of my species? Let me just say first of all, I really don't have a lot of hope for us. Maybe I'm being far too pessimistic, maybe its the music I'm listening to right now but I don't think our species, maybe even the planet, will survive with the invention of nuclear weapons, which in my opinion leave the world very volatile. I love the well known Einstein quote"I know not with what weapons World War 3 will be fought, but World War IV will be fought with sticks and stones," And that's assuming sticks and stones are left. (But then again, do I really care. Do I only have support for my species survival/revival? Or would I hope that any sentient creature could carry on learning?)
But putting all this aside, and assuming we don't blow ourselves up or get wiped out any time soon, is there a future for our species? A quick google search brought me to what looks like an interesting website. I haven't explored much, but I did find one article I quite enjoyed.While I was reading the article, I began wondering about whether or not a new, more evolved humanoid could evolve from us, or (somehow) emerge, and what this would mean for our future. The article mentions this briefly under "How A New Species Can Replace Homo Sapiens", specifically through positive gene alteration. If this could happen, I wonder where the line would be drawn to referring to a creature as a "human" or "person". At what point would we know that the emerging animals are no longer humans. I suppose once they are no longer of the species homo sapien sapien. But is it really our species that defines who we are. I would initially think of course, but say we come about some very similar creatures to us (through an alien visit, evolution, or whatever), do we call them human? Is it our physical bodies that makes us human? The way our mind works? What if some new creature has a mind that works almost identical to ours, but they exist in the body of, say, a giraffe, or some bizarre unknown form. Is it a human? I don't think it would be a giraffe. Is it something else? It begs the familiar question of what makes a person a person. I believe science (though admittedly I am not particularly versed on the subject) says that we are separate from apes and other animals because we are "sentient", which basically means to have emotions, be intelligent and conscious.

Moving forward, how do we even know if a knew human style hypothetical species would even consider us sentient? Maybe they are unbelievably more advanced emotionally, technologically and intelligence wise, and we are as simple dumb sheep to them? A bit unnerving to think about, no? Could we ever become a farmed animal? I'm not talking about a holocaust/genocide situation here, rather literally our entire race become subservient to some new creature, who might even look exactly like us, who might have been created by us! (Am I sounding to nutty at this point? Sorry.) I don't think we know for certain that it's impossible, and that's enough to make me at least slightly nervous, even though there's basically no chance of such an event happening in my lifetime.
Then I began pondering whether all of existence as we know it, possibly back to the big bang, is just a simulation in some other being's laboratory. It seems unlikely, but as far as I am concerned, it's impossible to know. I believe in the power of our science, but we don't know what it's limits are, even if we think we do. As a side not, if it sounds like I'm making a case for god, I'm not. Trust me. Never. I'm simply saying to my knowledge (and perhaps every human's knowledge for the rest of our existence) we can't rule out that we are not simply an experiment, maybe even an amusing past-time, like an ant farm for some order of alien race. Does that make me a deist? I don't think so, because I don't believe it's ruled out, or that it necessarily can ever be. So I suppose that makes me an agnostic...towards deism...yeah.
I'm sorry if this sounds pretty scatterbrained and isn't really very orderly at the moment. I never feel like organizing thought when I'm excited. I may edit this for clarity and add more content. Also, sorry for the sort of wonky formatting. I did my best.
Happy thinking!
