For evolution to happen naturally on genetic level, is a process that takes millions of years. It would take a concerted effort across thousands of generations of humans to see any meaningful change. The likelihood of this happening is nil to none. More realistic avenues of achieving something like what you talk about are likely through genetic engineering, nanotechnology integration, etc.
Epigenetics has shown how susceptible we are chemically and that those genetic changes are hereditary. We also know brain chemistry can be impacted by changes in how we use the brain. I suspect we'll be able to use these mechanisms to intentionally evolve faster.
How is it you're so very certain about how we work and the time scale evolution operates on when we're still discovering core mechanisms?
You may want to consider challenging some of these beliefs you hold because it sounds like they're limiting what you consider possible, which can only serve to limit your own behavior. A growth-oriented mindset is more helpful for learning and if we want to learn collectively, I think we'll need a lot more people with that kind of mindset.
If you don't believe it's possible to collectively organize to strategically change our thinking, will you be less inclined to orient your own toward the goal because "why bother?"
I believe there are simple, desirable ways to change how we use our brains and they're effective enough to get immediate benefits from them. That's enough for me to believe they're globally marketable, which is what it'll take to collectively organize.
