Maybe, but following the argument in the parent comment about the speed of transfer of information and physical goods, the timeline now may progress significantly quicker.
I suspect that the root cause now will be a technological failure, or more accurately, the inability of even a large group of citizens to maintain or re-build the globe-spanning technological structures on which our lives depend. It's an effect I've called the "Anti-Singularity" - at some point, some key component of this technological structure will fail for whatever reason, and cause a cascading and quite rapid failure of the rest of the system. At this point, progress and knowledge growth will very rapidly halt.
It's getting ever-easier to observe this!
