Recommended by Tyler Cowen, this story is a follow-on to a couple of recent posts, one on human progress and one on scientific groupthink.
We tend to think that human progress is defined by innovation and discovery, but the instant report clearly shows that it is possible for progress of that kind to simply end. Groupthink may be a cause, but the cause might otherwise be that Nature herself offers only a finite number of basic problems to solve. Or perhaps Nature is infinite, but the human mind is only capable of conceiving a finite problem set.
Another possibility is that scientific disruptions ebb and flow according to some rhythm we have yet to detect or understand.
A final possibility is that the disruptive science of the past has been erroneous to the point that new innovations will be impossible until we correct our mistakes.
