Lately, when asked how they see human civilization in the long run, some specialists often make an analogy. They claim that due to technological or biological evolution, the people of the future will be to us about what we are to ants. It is as if the quantity of the brain will bring new and new features.
For example, we would lack fundamental characteristics from the higher civilization, just as "understanding" is a characteristic that ants lack (of course, assuming this is the case).
Although I do believe more brain/technology can boost our capacity in quantity terms (e.g. a super-human could solve an equation trillions times faster), I do not think they will have something fundamentally new. My intuition tells me that once we obtain self-awareness and the ability of abstract, there will be nothing new under the sun.
I'd like to hear your opinion on that. Thank you!
