I'm a little disappointed that the internet and social media had little impact on universal disclosure about geopolitical matters. My sense is that governments updated their playbooks to both defend against them (e.g. minimize leaking) and leverage them (e.g. bury inconvenient information with propaganda). By comparison, I'm more hopeful about cellphones and bodycams generally reducing excessive police violence and discrimination (emphasis on "reduce").

prediction: the nuclear threat will look quaint compared with disposable million-drone swarms on land and in the air, targeting anything remotely interesting via onboard AI.
