I’m worried about this too. It wouldn’t be surprising if Trump dies in the next four years. Vance is not qualified for the job. He’s smarter than Trump though so scheming would be much worse.
This is why I've argued that technology, in terms of actual benefit for people, peaked many years ago. I won't try to pinpoint a date, but we have past peak technology from this perspective.
After that peak, advancements in technology have mostly just served as means to control the population or extract more from us (see enshittification) and have not been of benefit to the average person.
Technology allows for actual hard power to be concentrated in the hands of fewer and fewer. I don't mean like a dictator with an army behind them, but a dictator and small group with enough tech to control everything. You are right, and it's extremely concerning.
