I got a new laptop at work and everything, every file I worked in, was creating a second copy of itself on OneDrive. It was so annoying and took awhile but I found instructions on deleting the duplicates.
It took all the files off my local machine and left the ones on OneDrive.
Aaaargh!
I think populations will crash, either gently through fewer kids, or violently through war and disease. That will likely throw us backwards technologically, maybe not.
Or, who knows, maybe the population will stabilize and we get everything going in the right direction, then an asteroid hits.
