It will probably be a convergence of breakthroughs that will destroy humanity. Eg:
1) AI live speach will become indistinguishable from human speach. Then we can converse naturally with AI and not care that it is a machine (might be preferable in many cases—lol).
2) Other technology breakthroughs will marry up with AI. Funtional Robots, iphone 27 Pro++, Google Integrated Home, etc.
3) Innovators will deliver big time on unmet needs.
Here is one trajectory of converging technologies that could destroy humanity—The full life sexbot.
OK, we’re not quite there yet….
But when sexbots become soooo real they strut around, talk sexy and seductive, never ever nag, never get a headache or bad time of the month, are nympho’s and know all the pse porn moves and then some, carry a great conversation, listen deeply, have all the sports stats at their fingertips, align with my preferences for which teams win, etc, etc, etc., then we men will no longer need biological women.
Birthrates crash (profound societal sperm deficit). Humanity dies out in 2-3 generations, with a big shit eating grin on its face.
The End.
