2035-2040: all biological diseases, cancer, neurological diseases cured
2040-2045: aging itself cured, humans live forever just like AI and robots. Population explosion, not implosion.
2045-2040: human brain-AI interface achieves 100% integration, humans successfully merge with AI. There’s no more artificial intelligence. Only one synthetic life form. No more unnecessary human emotion: anger, lust, greed, etc no more hunger. Humans basic needs 100% eliminated, knowledge acquisition is the top common goal. Only then AI alignment problem completely solved because no more humans/AI boundary, no more misalignment by definition.
2100+ Absolute independent unit of intelligence getting much smaller, thousands/millions time smaller than nano meter 10^-9 for more information density and energy efficiency optimization. It looks like we are all disappearing into quantum realm. However, we are still well and alive. This also explain Fermi paradox because basically the aliens are invisible to SETI spectrum. “There’s plenty of room at the bottom” – Richard Feynman
2500+ Planck length 10^-35 reached. We understand gravity, hard problem of consciousness, causality, unify all current universe physical knowledge, forces and fields. We know now every single fundamental elements of the universe is actually conscious, even a rock, albeit at different levels of complexity.
