I really and reverently hope it will not be worse. Warfare on the scale and bitterness of the religious wars could be civilisational ending. The 30 Years War killed (directly and indirectly) about 25% of the population of the Germanies. I have no idea of the scale of the butchers bill for the Dutch revolt (the other major element of those wars) but I suspect it was of a similar scale.Yes. And this will be orders of magnitude worse than that. This will start modern wars with modern technology.
If you hadn’t noticed, most people still have the same relationship with the printed word. Whatever they see in actual print in meat-space or printed on the internet, they assume to be true. And act accordingly.
Which is why text, image, audio, and video created by “AI” will be such a big problem in future.
The Tudor and Cromwellian wars in Ireland were pretty awful also. Not as many people killed because there were not as many there in the first place.
