There will be no more countries. No borders. No passports. No visas. No wars between countries since there are no countries. It will be an age of peace.
Bigotry will be a thing of the past. No one will understand why people hated others who did them no harm because of color, gender, religion, etc.
All of today's major religions, except the LDS (mormons) will have disappeared. They will be replaced with other, more modern, religions.
All drudge work will be done by machines. Humans will only engage in recreational, artistic or scientific pursuits.
Everybody would be rich by today's standards. No one would need to work, yet they would still enjoy many luxuries, except for living space. People won't be living in mansions or anything, but they would have a personal robot that acts as a personal chef / a personal trainer / a personal assistant / an accountant / a majordomo, a personal shopper, a secretary, etc. Parents will have a separate 24/7 robot nanny to help raise their children. All things only rich people today can afford.
People will be post-Cyberpunk. The good kind that doesn't have sparks and cyber-psychosis but mostly genetic engineering. We will no longer be Homo Sapiens but a different species. We will be able to jump like cats, cancer won't be a thing, eternal youth is a given and no more natural death. All death will be artificial (suicide / accident / murder)
Babies will be grown from donated sperm/eggs, in artificial uteruses, then decanted. There will be no such thing as pregnancy or giving birth and they will be seen as obsolete. All genetic diseases will be cured in the machines. All babies will be partly designer babies.
We will have sent nano-bots to Mars, Venus and the outer systems to warm them and oxygenate them up to human standards, then we will have sent androids to terraform them further. There would now be colonies in all 3 places. We will exile our criminals to the outer systems.
All videogames will be VR. Your CPU and GPU will be in your skull, as well as a full Dolby Atmos system. You will be able to disconnect your hearing or pain sensation at will. No more noisy nights or snoring! Just set a subroutine to turn off your hearing when snoring is detected. When bored on the hyper-train, you can hibernate your brain like a laptop until you arrive at your destination in one (subjective) blink of the eye. Everybody can wirelessly have sex and it's identical to the real thing.
Either that or mad max.
