What the author meant by innovation seems to be limited to world-changing innovation like the telephone or internet. Following that, I’m unsure if world-changing innovation is slowing down primarily because of the talkocracy. The issue is not exactly about innovation slowing down because of X or Y, but as more and more innovations are made, the time needed to get to the next innovation will potentially increase. Each innovation introduces yet another complexity we need to handle, and unless we can keep up with the new complexity on top of the current set of complexities, we’ll just have to contend with the slowness.

It’s possible at some point that the complexity is too big, no amount of talkocracy purge can allow us to replicate the innovation speed of the past.
