Like for example, as soon as meme stocks dive in the next recession, most likely the reddit groups based around this will fall apart because the idea that meme stocks are a great way to make quick money will die.
I think the shape of the group changes, those with more deeply held beliefs about a group will stay and perhaps "regroup", but for most, who get attracted to a particular group for no clear first principles, they will leave and from their perspective, the group has definitely died.
But to use the meme stock example above, those who were in the group because of deeper beliefs that meme stocks signal a shift in retail trading and the rise of the consumer need for financial independence early on tied to the lowered barriers of financial transactions thanks to the internet, they will regroup.
Ok back to work
