I suspect that for U.S. studios partly it's the destruction of writers' rooms, the end of TV writing as a career, and the resultant loss of expertise and mentorship.
Also gritting their teeth that it's getting increasingly impossible to signal "this is a totally over-the-top bad guy" in fiction.
I love the idea of finding actual stakes that matter, since the Doctor will never die but Companions get routinely sidebarred.
First they need someone who can write.
Modern civilization relies on interconnections of many highly specialized pieces, and without the ability for different polities to interact and trade, it's hard to sustain. Supplies break down and run out. Replacements are impossible to make. Knowledge becomes lost.

As a result they look to Rome because it's dramatic and imperial and conquest-oriented, instead of looking at peasant revolts, which were incredibly common and bloody. They want to be emperors and priest-kings, but emperor of what? A tiny survival bunker of a hundred people?

These tech billionaires always go for the flashy, high-concept sci-fi, like cities on Mars and consciousness uploading, and they decry the logistics of boring material existence, like making sure that people are fed and housed.

Anyway, just another example of their humorous ignorance. They all think they are going to live like kings in tiny castles, but even kings required the support of thousands of people in functioning communities spread across the land. All these bunkers are doing is making some construction co's rich.
That's why it's so important to generationally transmit knowledge and to encourage problem-solving skills. Otherwise you wind up run by dolts who accidentally poison the entire water supply for everyone and you have nowhere to go for help.
