In the immediate future (all of our lifetimes), I see a rise in narcissism as resources become scarce. Already, people like the Bushes and T Boone Pickens have bought up the water supplies. Everyone will not only be drinking bottled water-- they'll be carrying oxygen tanks too. C-Pap machines are just the beginning... we'll start to see them during the day too, due to a combination of environmental air pollution and people growing too obese to breathe.
In the slightly farther future, I foresee autism becoming the new normal, and the normal people being medicated with psychotropic drugs so that they can interact with the autistic majority. Biometrics will rule everything, so people may display their IQ and SS# on their shirt as a name-tag. Like, we may be called #123-45-6789 instead of John Smith, which is just as well, because of all the people naming their kids ridiculous things. I think many languages that we know and love will be extinct, such as Italian, Greek, most of the non-Russian "satellite Slavic languages," and most (if not all) Native American languages. This may facilitate communication in practicality; however, we will lose culture.
Medical science will still be useless quackery, done to maintain you (or make you worse) and not cure you. I've been in chronic pain for 25 years. I don't foresee them curing things like chronic pain, cancer, diabetes, or autoimmunities anytime soon, particularly because it's the bad food that makes us take the drugs. Soylent Green is true. We've got GMOs, sugar substitutes/MSG excitotoxins, high fructose corn syrup, farmed fish, and a very disgusting meat industry going on already. Also, if we mess up the environment, then we are all eating that because that's where the food was grown. I think they actually want reduced lifespans for everyone. Only the rich will be "immortal," because the rest of us won't be able to afford it. We'll have all to do to afford our algae-powered autonomous vehicles, which will probably run $100K, plus our mortgages and massive future student loans. The debt of the future will probably continue doubling exponentially the way it is doing currently, which means it becomes more and more impossible to escape the slave pyramid. People may have to live in communes as a way to pool resources, or be like those people on the Sister Wives, lol.
In the distant future, child-bearing capacity will be reduced because the food is set to make us infertile within the next generations. People will be applying for child permits and going to the lab to buy engineered babies if they can't make their own anymore. Brain implants may be used for those who are naturally born, since their intelligence will not be even close to the engineered babies. We've had brain implant technology since about 1970, but this will be even better.
Overall, I think we're looking at earth not being able to keep up with human destruction. The only mechanism that the earth has to keep us in check is the weather, which will of course, result in chronic hurricanes, snowstorms, earthquakes, and sink holes. Sink holes will not just be in Florida; they'll begin to pop up anywhere that fracking existed.
The question is... do we send the "least valuable" people to the moon (such as prisoners and centenarians), or would the elites want the moon solely for themselves as an exit strategy? I'm not sure how to call the moon, but I'll guess that the elites want to be the ones to go there, and leave us here.
