The atheist generation will have grown up and begin to look for someone to tell them everything will be okay. It's a good opportunity to start a new religion.
A new religion based around what? Is this religion supposed to actually be believed? This is one of my favorite videos which explains why new religions don't have as much credibility https://m.youtube.com/watch?v=PEg_Oys4NkA You have to watch the video to probably get the basic idea. I'm not Jewish despite the video focusing on Judaism.
Which direction is the zeitgeist blowing? From my perspective, it seems that there is a real and ongoing erosion of local communities (labor, religious, or otherwise) that are replaced, often times, by a shallow virtual existence. It does not have to be a religion in the conventional sense, just something that attempts to give meaning to the meaningless.
