On top of that, I have the subjective perception that the world keeps getting more and more complex and difficult to fully understand. There are way too many loops of information to be deep into

I think you would get over that perception if you attempted to live in a primitive style for a while. Hunting and gathering food while avoiding predators, finding mates, and staying warm is as complex as anything we do routinely in the modern world.

And even if it were less complex under some rubric, the complexity of such primitive skills is still more than sufficient to saturate our capacity for it.
