Multiple hominid species on Earth have had a technology gap on an unfathomable timescale. Indeed, the Denisovans developed stone tools tens of thousands of years before our own species.<p>We often look to the stars and wonder what other intelligent life is out there. I'm sure it's captured every one of our minds at some point. Dark Forest theory of the Fermi Paradox be damned, we want to share in the comfort of knowing that intelligent life exists. That we are not all alone.<p>But I wonder - had things been not much different, might we be cohabiting with an intelligent species, one perhaps tens of thousands of years ahead of us? Aliens on our own planet?<p>Would we even realize their sentience - would our minds even be comparable? Would their civilization fade to ruins before we came to sentience, and would we discover remnants of a long-lost civilization? Would they raze the planet to the ground and never provide us the opportunity to develop sentience?<p>So many questions. Are we in a similar situation right now with other hominids, who we've found to have a "theory of mind"? Are we morally obligated to not cut the nip of societal development in the bud for these species? And if this species suffers in developing and advancing, are we obligated to ease and accelerate their development?<p>For example, if a far advanced civilization was out there, merely observing us while they knew they had the cure to our dying loved ones and general suffering on this planet, would we not find the only ethical solution to provide said cure? As such, are we in a similar situation with other developing hominids?<p>When you think about it, it is possible that intelligent life developing on other planets is not a singular species but multiple species. And that's fascinating. I wonder what it must be like, to cohabit with a different species that is effectively your equal with respect to self-awareness/sentience, even if they are not your equal with respect to technology.
