Reasoning it through, what don't people politely talk about? Sex, money, politics, and religion. Sex: the impact of the normalization of casual sex work on sustainable families, and how specific tech and financial services for managing single motherhood will be huge. Money: financial alternatives to emerging social credit based systems, grey markets, working class capital/savings flight, cyberpunk dystopia. Politics: polarization becomes relative isolation, increasing demand for parallel tribe-based economic and information services. Religion: pendulum swinging back from civic secularism among those disenfranchised by said secularists. Reconciliation of old time religions with current tech and science. The christianization of fringe ideas like "ancient astronaut theorists," conspiracy theories, simulation theory.
True or not, they're big and not talked about in polite company.
