Human Intelligence and free will are something that fucks those three points up. Those alone classify human beings.
We have the potential to control the natural environment and shape it to our needs.
As you've write, we don't need our body to evolve anymore. We have the potential to improve it with our own technology.
We ultimately have the "potential" to understand how to modify our bodies, or even to create new ones to replace ours according to our likings. That would be "eternal youth", and we'd be set out the cycle of "life and death".
I've write "potential" because we can do that but we're still far from it.
And that is simply because we're way too busy gaining money, power and fucking each other up (by and in every meaning possible).
Each society has sucked a lot so far. We have only had boosts in science thanks to very short periods of grace ( usually allowed by those who holded power), if compared to the whole history of mankind. So, if we do exists since about 10000 years ago, we've only spent an extremely small percentage of those years doing some serious efforts in science, and the 95% of those efforts were made in the last 300 years.
Since achieving a "dream" society is probably a task harder than gaining "eternal youth" but
What if there were worldwide peace and economical stability?
And if there were like 1000% more scientists, engineers, and technicians?
What if a much bigger Research budget was entirely spent on serious research? ( instead than garbage like "How many times a day a man farts" or "Why do men are attracted by younger women?").
