Proto AGI/First generation AGI is created: This is a AI is almost certainly many times dumber than humans but it is actually general and actually learns in a general way like humans. The two smartest futurists focused on AI that I know have ether said before the end of 2024 or backed the before end of 2024 prediction as reasonable. (Socially I don't understand if it is good or rude to share others predictions.)
Human Level AGI: AGI will eventually be improved to human level.
End of the GAP: The GAP is a concept I have been thinking about but I am sure other people have came up with it before me as I am just some idiot on the internet. The GAP is a period of time probably lasting a few years maybe 5 where Human level AGI has been created but its impact on science and technology is low. A human level AGI is just going to be one additional super expensive human it will take some time for Human level AGI to become cheaper and much smarter than humans so it can impact science/technology in a meaningful way. A human level AGI will research AI slower than a AI researcher as AI researchers are smarter than most humans and have better body's than robots/computers as well. Outside of science there will still be major impacts in areas such as politics as people will be basically shitting their pants in fear or excitement.
End of depression for most people: The world has developed to a point where its unlikely people will be unhappy for a extended period of time, most people now just enjoy life.
Utopia: You now have everything you specially want, this is different for everyone but as we are all humans it will likely occur around the same time for most people.
Perfection: Science has been perfected hopefully we can prevent the death of the universe and also make our own death literally impossible.
