Reading the "endgame" section, and I feel that some serious thought ahould be given to what the replicator colony will do after it has finished dismantling Mercury.

Pretty sure the idea predates that lecture, it appears in Charles Stross' novel Accelerando from 2005 (which is based on short stories that were published years earlier).

I think I must be missing something important, because this doesn't make sense to me. If you put your mirrors in orbits where they don't block the dayside surface (sun-synchronous?), then they increase the total surface area receiving solar radiation.
Yeah, orbital mirrors essentially expand the radius of Mercury, increasing the sunlight available. Terrestrial mirrors would ensure that light makes it from the sunward side to the dark side of the planet.
Why does being so deep in the gravity well pose an issue? If you are assuming the Dyson swarm is intended to go back up the well then sure, but that isn't necessary.
Could you elaborate? Why would being deep in the gravity well be a non-starter? I thought Mercury's proximity to Sol was a huge advantage because of the ample solar power which would make planet-side manufacturing easier.
I encourage Dyson sphere enthusiasts to listen to the interesting argument that Dyson spheres they may be deliberately designed as an "sounds neat but is impossible" filter joke, ref: https://www.youtube.com/watch?v=fLzEX1TPBFM .
Sped through that, couldn't stomach the whole thing. Is there more to it than "argument by sneering dismissal"? (Basically, so far as I can tell, her point seems to be "this was intended as a joke to see if you're stupid, so if you believe it, you are, neener-neener!")
I guess it might. I wouldn't plan on it without a very detailed survey though, to say the least. Whereas solar is definitely right there. (And you still have to worry about cooling either way.)
There are other substances that can be used for reactor coolant. Molten salt reactors are actually substantially more efficient than water-cooled reactors because they have a higher operating temperature. You can also use liquid metal as coolant, such as lead or bismuth.

If someone can't be bothered to write it I can't be bothered to read it.

Roger that
This reads like an LLM plagiarizing this video from Kurzgesagt:

Kurzgesagt didn't invent the concept of disassembling Mercury to build a Dyson swarm. Stuart Armstrong proposed it in a lecture in 2012[0].

Bootstrapping an electronics supply chain on another planet seems harder than building the dyson swarm itself.
Just let Claude figure it out

this seems to ignore the fact that Mercury is way too deep in Sol’s gravity well to be useful, all it’s looking at is Mercury mass.

1-6 years can't be realistic can it? does someone have a better estimate of how long this would take?
50-100 years default, 25-50 with Plan Mode, and down to ~10 if you use Opus 4.6 Max

Somehow I new before clicking that it was going to be Angela.

Stuff like this is why I read HN
What about orbital mechanics? Wouldn't that create issues with/for objects in the solar system?
Does Mercury not have any useful radioactive material to provide more power?
I guess it might. I wouldn't plan on it without a very detailed survey though, to say the least. Whereas solar is definitely right there. (And you still have to worry about cooling either way.)
Are there reactor designs that could work up there? There's not much water for coolant.

Please someone, send grey goo to Mercury.
I am such a sucker for technical Aspie writing. I've seen it mistaken for LLM output many times but this is not that.

its not? how can you tell?
