Elon Musk's opinion the concept( not this one in particular though ).

Let me tell you one of my pet peeves: space solar power. Okay, the stupidest thing ever. If anyone should like space solar power, it should be me. I got a rocket company and a solar company. I should be really on it, ya know. But it's like, super obviously, not going to work because, ya know, if you have solar panels - first of all, it has to be better than having solar panels on Earth, so then you say, okay, solar panel is on-orbit, you get twice the solar energy - assuming that it is out of Earth's shadow - but you've gotta do a double conversion. You've gotta convert it from photon to electron to photon, back to electron. You've got to make this double conversion, so, okay, what's your conversion efficiency? Hmm. All in, you're going to have a real hard time even getting to 50%. [The solar cells are better.] It does not matter, put that cell on Earth then. See, that's the point I'm making. Take any given solar cell, is it better to have it on Earth, or is it better to have it on orbit? What do you get from being in orbit? You get twice as much sun - best case - but you've got to do a conversion. You've got to convert it the energy to photons - well, you have incoming photons that go to electrons, but you - you've gotta do two conversions that you don't have to do on Earth, which is you've got to turn those electrons into photons and turn those photons back into electrons on the ground, and that double conversion is going to get you back to where you started, basically. So why are you bothering sending them to bloody space. "I wish I could just stab that bloody thing through the heart." BTW - electron to photon converters are not free and nor is sending stuff to space. Then it obviously super doesn't work. Case closed. You'd think. You'd think case closed, but no. I guarantee it's gunna come up another ten times. I mean, for the love of God.


I read it a few weeks ago. It is very good and highly recommended. I feel this opened my eyes quite a bit in the following ways:

- history is not a linear progression and narrative, sometimes things happen in leaps and also can go "backward"

- farming was something that was dabbled in for a millenia before fully committing to it

- the idea of "egalitarianism" is quite vague and can be understood in many ways

- ideas about egalitarianism moved from native americans to the french .. not they other way around

- lots of very interesting stories about how our ancestors were not stupid

- lots of questions about how archeology has been interpreted and how a lot of the evidence does not support the mainstream narrative

- gives examples of societies where "leadership/politics" was actively avoided

- has a nice background on different ingredients of statehood and how they manifested in history

I have a feeling this might be the seminal book for having a fresh analysis and reassessment of lot of what is called "prehistory".

Very highly recommended from my side. I will re-read it a few times probably and gift it to a few friends.


Google (okay, Alphabet) is the only big tech company that I can imagine would ultimately _benefit_ from an antitrust breakup.

Google keeps killing low-to-medium profitable smaller product lines and tools because it can't spin them off successfully. Google can't spin off tools successfully because their internal codebases are deeply reliant on assumptions about Google's infrastructure and Google internal libraries, etc. (for example: Google Reader could not be spun off because it assumed things about Google's infrastructure + libraries.) So Google arrives at this strange position where medium-yet-small profitable products can't be spun off or divested because of Google's secret sauce (their internal infrastructure). So Google kills successful products instead, because it isn't interested in scaling up an only _modestly_ successful product.

This is insane and a sign that something is deeply wrong in Google. Splitting Google up, forcing this infrastructure to become open, etc would be much healthier than perpetually killing small products to protect Google's secret sauce.
