The Open Question March 18: How do we reason about the future given AI? I find this topic extremely perplexing, and endlessly fascinating.
- What are we raising our kids to be ready for? What skills don't matter anymore that we used to hold sacred, and what do we need to emphasize?
- Will we have universities?
- Where to invest time/energy?
- Where to invest money? Will money even matter?
- Purpose and meaning, etc...
especially when I factor in stuff like Nate Soares talking about If Anyone Builds It Everyone Dies, Rob Miles and Jeffrey Ladish communicating the wild risks involved in AI acceleration, there's almost too much to contemplate at once, and I'd love y'all's help.

Good call Jay. This reminds me that apparently Darwin mentions the word "love" 95 times in his book The Descent of Man in contrast "survival of the fittest" (twice) in the same work; once to apologize for saying it....

I think our difficulty comes from making something complex and difficult that is actually very easy. What kind of future do we prepare our children for? Excellence in human relationship. That’s not going to change. Whatever else changes, that will always be the same.... Evolution or Extinction
Today is Charles Darwin's birthday. It has me thinking about his core idea of "survival of the fittest" and how the concept is frequently misused in business. Fittest does not mean strength. It means the most resilient and adaptable in a particular environment or ecosystem.... looks like I've been wrong and spreading misinformation about the disproven "triune brain theory".
The final—and most important—problem with this mistaken view is the implication that anatomical evolution proceeds in the same fashion as geological strata, with new layers added over existing ones. Instead, much evolutionary change consists of transforming existing parts.

I have definitely made this mistake, many many times.
I'm not sure yet the implications of recognizing instead that "all vertebrates possess the same basic brain regions, here divided into the forebrain, midbrain, and hindbrain;" in some ways it seems like a nuance, but in other ways I think it'll shift how I see things and talk about things.
more quotes in case you don't read the article:
neural and anatomical complexity evolved repeatedly within many independent lineages
the correct view of evolution is that animals radiated from common ancestors (Fig. 1c). Within these radiations, complex nervous systems and sophisticated cognitive abilities evolved independently many times. For example, cephalopod mollusks, such as octopus and cuttlefish, possess tremendously complex nervous systems and behavior (Mather & Kuba, 2013), and the same is true of some insects and other arthropods (Barron & Klein, 2016; Strausfeld, Hansen, Li, Gomez, & Ito, 1998). Even among nonmammalian vertebrates, brain complexity has increased independently several times, particularly among some sharks, teleost fishes, and birds (Striedter, 1998).
The idea that larger brains can be equated with increased behavioral complexity is highly debatable (Chittka & Niven, 2009).
thanks, yeah i agree this physical membrane thing is often lost in discussions of "collective intelligence" in the integrally oriented community, despite Ken Wilber directly addressing it a few times in various essays.... looks like I've been wrong and spreading misinformation about the disproven "triune brain theory".

I spent a lot of time in the "Integral community" in which all the pre-human (or pre-noospheric) stages involve physical membranes that enfold previous layers of structure. Cells are literally enclosing molecules.... looks like I've been wrong and spreading misinformation about the disproven "triune brain theory".

Is having children a selfish or a selfless act?
I'll put my thoughts in comments - would love to hear yours :)
For me personally, I felt this having kids. I could think about having a common ancestor with a banana (50% of our DNA is the same) but I couldn't feel it. Now I feel it.... Is having children selfish or selfless? Controversial question/interesting discussion time!

Can I push on your perspectives a bit? I wonder if it's accurate to frame the "felt sense compulsion" as selfish? Maybe it's much bigger than the individual, an evolutionary force being pushed through each of us in different ways?... I don’t fully understand what sexual attraction really is. In one occasion I was able to pierce through a feeling of arousal and I found a big wound from my childhood. Something totally non sexual.
I wonder whether a lot of sexual attraction just points to unmet needs and is “designed” to help us meet those needs by bringing closer to specific people (with certain characteristics).
But I don’t understand the whole picture here. Is it always like this? There is some clear use for sexual arousal in reproduction, I can’t believe that’s always a sexualized childhood wound. Where’s the border between a sexualization and a genuine, irreducible sexual thing?? What do you think?
I've also thought about this and seen similar things. I think sexuality is extremely deeply tied into all our machinery because of evolution, so I'm sure you can find examples of all sorts of complex configurations.... Experiment: How is whatever's happening serving the greater good? If we zoom out long enough, we can often see that massive setbacks created foundations for evolution. Eg:
- The great oxygenation wiped out almost all life on Earth, but also created the atmosphere.
- The extinction of the dinos paved the way for bigger mammals—and eventually humans.
- Industrialization put tons of people out of work and polluted like crazy, but coincided with some of the greatest quality of life increases in recorded history
- In Trump and a Post Truth World, Ken Wilber suggests that Trump’s 2016 win was one manifestation of evolution taking a step backward to correct the way the “Green meme” went unhealthy—because the one thing that Trump was coherent about back then was being anti-pluralistic.
What’s a thing in the world that you don’t like right now, and think is a huge step backward, that might also be a step forward? How so?
By design, this is an unverifiable experiment from a third person perspective. Since we can keep zooming out + everything is interconnected, we’ll probably never know for sure, even if we live for thousands of years.
But by design, this is verifiable from a first person perspective: Does your experience improve or change in any way by the experiment? How so?
(note that this doesn't ask you to deny any suffering—such as the horror of the oxygenation event's great extinction, or stop trying to make things better. Like everything, this perspective can be misused. "Everything happens for a reason" is usually dismissive, "if there were a reason for this in the long run, what might it be?" is additive. Like allowing versus expressing, it's not about bypassing the difficulty but rather creating a larger container for it. Freedom comes through acceptance rather than resistance.)

Awesome, thanks for pointing me to both exaptation and this Kauffman book. Man there's a lot in exaptation; I'm in a cafe right now that used to be a filling station/garage and I love the garage doors that they can open and close to bring in the outside world when the weather is...
