There was a chance for another "dark age" many times through the past 2 centuries. Hell, there is a good chance we are entering another dark age now as we speak. It's just we aren't aware of it because the process is too slow for the evidence to pile up until it reaches the critical point where we would realise our society is actually breaking up piece by piece. (But it could take a century or two until this collapse materializes, so it would be pretty damn hard to pile up the evidence before it's too late to do anything about it.)

Even after a warning rattle, right back to the same thing.
We'll go with straight out of the gate.
We divorce you.
To Coventry with you.
