Those jobs are also being replaced by AI. Modern AIs are trained on synthetic data, which is data that was generated from source material specifically for training purposes by other AIs. AIs reformat, rewrite, and vet the source material more reliably and efficiently than humans.
IMO the best feature of democracy is not that it results in better selection of who gets to lead, because it doesn’t really - the vast majority of the electorate is not educated in the sorts of things they’d need to be educated in to make truly good decisions about this. The best feature is that every few years we “throw the bums out” and put a new batch of people in charge.
I used to be kind of ambivalent about term limits, I figured it was kind of suboptimal to have to get rid of a leader who’s doing well at some point. But with the size of the population of most democracies there’s really no constraint on the pool of perfectly adequate candidates to draw on. I’m starting to think that “one and done” might be an even better approach, at least for the highest levels. Make it so that there’s no motivation whatsoever to cling to power. Do the same with congressmen and senators, perhaps. Let them prove their capabilities with a political career in local politics, where it’s less important if someone ends up with some kind of corrupt fiefdom because the higher levels of government can keep them in check.
