Go bust, as in 'out of business'? Unlikely. They may downsize, they may reorganize, but the religion will continue to do the same thing it has always done - reinvent itself in order to stay relevant (at lease relevant to people who believe in it)
Now - here's a fantasy to dwell on for a couple of minutes.... what if the entire GB were arrested for fraud, cover up, something, anything... the kind of scandal that brings down powerful leaders and icons.
Oh sure, there'd be a few diehards that would refuse to accept the reality, but by and large, for many it would be the catalyst to dig deeper and realize the folly of their belief system.
Highly unlikely to happen, but oh well, it's fun to think about for a couple of minutes anyway
