What's also annoying is that sizes of the same clothes change.
I have a pair of jeans that I ordered on Amazon in 2020. It happens to fit me great. So recently I decided to order two more of the same. I got exactly the same model with the same size on Amazon, just with different colors. But neither fit very well, they were far wider. The first one had such a horrible fit that I immediately sent it back. The other I can wear, but it's quite different from the other perfectly fitting one. Why are they doing that? It's insane.

How do we know the Cambridge Philosopher is conscious?

I don't feel his overflow miscompilation example is a good one. A 64bit multiplication converted back to 32bit has the same overflow behavior as if the computation was in 32bit (assuming nobody depends on the overflow indication, which is rare). And in high level programming languages you typically can't tell the difference.

I’m curious if any of these centrally planned capital city relocations have succeeded. Brasilia, for example, is widely considered a terrible city. Are there successful examples?

Thats the pascal kernel in all its glory. Its just a bare metal hello world

I'm curious why humans evolved intelligence and chimpanzees, gorillas, orangutans did not.
chimpanzees, gorillas, orangutans evolved intelligence too. They are smarter than most other critters in the jungle. Just all not as much as the lineage that leads to humans.
It's actually quite difficult to define human intelligence. Every time we think we find something unique by humans eventually some animal turns up that can do it too. It may be all just a question of degree and how it's used.
Most communications satellites (which is all Starlink really is) are heavily focused on their operating bands and any specific bands they are told not to interfere with so they can get launch approval. There's no benefit to doing anything extra. And not only do they have to be told which specific bands they can't interfere with, the government actually has to require delivery of test results or else that is the same as giving permission to interfere.
Most companies won't spend a penny, take a second of time, or add a gram to a satellite if it doesn't affect their mission or chance of approval. Especially not one as cost-optimized as SpaceX. They won't change a thing unless the US government forces them to do so, or if they think that a government order is imminent so they come to some voluntary agreement ahead of time to avoid what would probably be a more constraining official regulation in the future.
The actual issue is probably caused by switch-mode power supplies or some digital signal on the satellite that isn't fully shielded, possibly one that does digital control of a motor or thruster. It probably isn't the communication radios since they operate at a much higher frequency. You can fix the issue by adding filtering and/or shielding, but that takes extra components (meaning extra cost and weight) and requires testing (meaning time). Plus you have to identify the offending system, which means you have to start with testing and detective work. This interference was only detected on some Starlink satellites, so you have to do detective work to find out if it is a particular operating mode or generation of satellite that is offending, do testing to confirm it, and then work on a fix.
This is actually not correct for Starlink. They did a lot of work to lower their albedo based on astronomer complaints, even though there wasn't any government regulation in this area.
It might apply to some of the emerging Starlink competitors however, especially the Chinese ones and AST.

Cool concept, but some things are just strange:
Power provided by toroidal nuclear fusion reactors in the outer shell of the living module, but why do you need such reactors if your primary propulsion is provided by Helium 3 - Deuterium Direct Fusion Drive? If you have direct fusion technology, you don't need toroidal reactors.
Rotating inner shells mechanically for 400 years is terrible design, it's much easier just to rotate entire structure. Once it's going it keeps rotating inertially!
Another comment points to error in speed calculation - at declared acceleration they should go at 0.1c, not 0.01c!
And what is missing of course is the calculation of how many years of current world's GDP is required to complete such project event if all yet-to-be invented technologies exist.
If you would spin the whole structure you couldn't have multiple shells all with 1G on their surface. The required spin speed for 1G depends on the diameter. But their whole concept is built around multiple shells, which is clear from the name.
Regarding the GDP needed once you have a working "mine from the moon and send to orbit" economy it doesn't seem to be too bad. The assumption would be that a lot of technology is already developed for other projects. Launching it all from earth obviously wouldn't be possible even with vastly cheaper launch. That's why they put the build into the moon-earth L1 lagrange point to be easily reachable from the moon.
For propulsion and reactors, but there are multiple projects today working on all of this. Building a life support system for 400 years is still an unsolved problem however.

I'm so used to seeing the "fish crawling onto the shore" cartoon of evolution that I assumed the branching always went that way - land creatures are branchoffs of sea creatures. But surely this is oversimplified - are there examples in the other direction, where a branching occured in land animals and one branch then returned to the sea?
There are also lots of extinct examples like Ichthyosaurs, Mosasaurs, Plesiosaurs
Modern examples are saltwater crocodiles, sea turtles or sea snakes
