Huh, I seem to be getting something way different from this comic than most people here...
I'm seing knowledge being transferred, and as the number of sources and amount of information increases, it gets harder to figure out how everything interconnects and how it all fits together. But as you get older, you get more experience and start to see how things fit together and the world makes more sense. In the end the jumbled information you've received through your life makes more sense to you, and you transfer the new sum of information on to someone.
As a beginner, you learn and memorize the basics.
As an intermediate, you experiment, inject fresh energy into sketching and exploring outside the basic parameters.
As a master, you have returned to basics but with a unique perspective, your added experience to the narrative.
I feel like the more experiences I get, and the more experiences I learn of from other people, the less the world makes sense. The more I sit alone stuck in the echo chamber of my skull’s interior, the more experiences I can easily discount and ignore.
I don’t think anything about the world is simple or easy to understand, and I get worried when I start thinking that I have life boiled down to a few simple rules
To me it's not end of the story that's the point of this, but the idea that when you are more social and engaged with different ideas your mind is more creative and energized and flexible. And there are other times, especially as you age, where you are more isolated and your mind slows and gets trained into rote thoughts. They may or may not be the same ones you started with, and they may be well earned and refined thoughts from a lifetime of experience, but stripped of the complex context they arose in, they are still just a simplistic starting point for the next round.
I don't think that's the point it's making, that the old person has a closed mind. Just that they seem to have ideas and values which seem e.g. morally ancient or something similar, but by the time you reach their age your values and world view will have changed to probably be very similar. I don't see any values being placed on what they are thinking.
