Humans have a natural tendency to be drawn towards spiritual beliefs and practices, and I don't think that we'll ever see human society without religion. Whether that's a good or bad thing is certainly up for debate. I know it's overplayed, but I do think that there's something to be said for spirituality vs religion. Religion usually points towards organized religion: doctrines, rites, taboos, etc. Spirituality is more an individual's personal, introspective experiences. Spirituality is always an aspect of religion, but religion is not always an aspect of spirituality. I believe that a personal spirituality can be very helpful for helping one to look inward and consider the universe around them in different ways, and can also help one to see that we are all connected beings that should be kinder to each other. Community and support are good aspects of religion. Deeply-held dogmas and organized endorsements of hateful thoughts and behaviors are negative aspects of religion.
Overall, I think we'd be a more interconnected, peaceful, and loving species without religion. But I have a lot of personal bias in that answer and there are way too many variables to really know if that would be true. Religion isn't going anywhere and it's not necessarily good or bad, and does a lot of both in the world. Things are very rarely black and white.
