To my knowledge, the sapient population is the human population of Earth.
However, there are numerous sentient species that could conceivably be “uplifted” in the next thousand years. Plus, I consider it more likely than not that extraterrestrials do exist and that there’s likely another sapient species out there, though they are unlikely to be in our general volume of space
Same here. Been together 8 years, and from the sounds of it they got terrible ~7 years ago.
