Artificial intelligence and its personal meaning to me

At their current, exponential rate of improvement, it is predicted that physical limitations in the human body such as strength and endurance will be vastly reduced due to nanotechnology modifying our genome and reprogramming our bodily systems. The human brain will have been entirely reverse-engineered allowing for mass replication, and artificial intelligence will be powerful enough to tackle problems as general as the human brain can, only with input & output speeds that are millions of times faster. I'll be 60 by then, which will probably be half the life expectancy of the average person. School children could outperform Olympic athletes. Families could grow to enormous groups of people spanning many generations.
