Organized religion makes a fool of the wisest of us. Jesus, Buddha, Lao Tzu, etc. All their philosophies are similar and can easily be agreed upon by the majority of the world, and yet, 1/3 of those is obsessed with converting the world to their particular philosophy. That's literally the reason the church exists, at least on paper. In reality, they want as much power as possible, and for a while, it looked like they'd get it.
Then we turned to science and rationality instead. I honestly couldn't give less of a flying f*ck what you people believe. Most atheists i've seen/met seem to share this sentiment. As long as your silly beliefs don't f*ck over everyone else, it's not an issue. Personally, I find the very core of 'spirituality' to be complete nonsense, given that 'souls' don't exist. Christianity's future is likely the same as every other religion that came before it. Eventually, it'll be replaced with something else.
