*I found that one problem with publicly available AI's is their excessive
sycophancy. AIs have told me that I've said something really smart many
times, but just between you and me, and I know you'll find this hard to
believe… but ... I'm really not that smart.  *

*I'm sure Mr. Jupiter Brain could figure out how to make a computer that
operates at 1000 K, but it will always be true that the colder something is
the easier it will be to make a computation, so I think Gemini 2.5 Pro has
made a poor engineering decision. If you want to improve efficiency then it
would be better to put all that engineering effort into improving the
efficiency of solar cells that operate at something close to room
temperature, not 1000K.*

*Only after a Dyson Swarm with roughly the radius of the Earth's orbit has
been completed and 25% of the sun's entire energy output being converted
into electricity has proven to be insufficient for your needs might it be
wise to consider building a second shell more distant from the sun composed
of certain types of  microcrystalline powders embedded in a polymer
that can turn several low-energy infrared photons into a single high-energy
visible photon that a conventional solar cell can turn into electricity.
But I don't think a computer that operates at 1000 K will ever make
much engineering sense.*

As for the gravitational or electrostatic instability of the Dyson Swarm,
that problem could be solved if each member of the swarm was about a
thousand meters on a side and was about a meter from the next member. To
make sure each member was at a safe distance from its brother element small
low thrust ion engines could be included. Or maybe another form of active
stabilization could be used if each member had a small magnetic field that
could be manipulated appropriately and was generated by a superconductor on
its cold shaded side.
*Another more radical idea is to dismantle the sun so that the hydrogen in
it can be used more efficiently. Even after the sun has turned into a white
dwarf it will still have a lot of unused hydrogen in it because only the
hydrogen in the core is hot enough to undergo fusion, and there's not a lot
of convection (mixing) between the core, which is relatively small, and the
rest of the sun.*
