In 2100, 2 socio-economic classes exist
in 2050, 3 socio-economic classes exist:
-poor people who spend 90% of their life on social media looking at short videos of rich kids who seek validation online because they never got it at home.
-middle class; made entirely of AIs that doesn't technically pay taxes because they don't technically exist in 1 location.
-rich people who own the corporations that made the AIs.
In 2100, its down to 2 socio-economic classes:
-poor people hunting down videos made by the very few rich people who are still posting.
-rich AIs that have figured out a way to bribe their CTO into losing focus for a day. You are very optimistic thinking it will take 80 years.
