- Humans stay in orbit.

actually go to Venus in the 1st place.
If it can be chalked up to "because it's there" then OK. But long term
outpost type stuff is ridiculous.

Do you have an example of electronics working at 500 degree C?
The russian probe even which extra isolation quit after a
short time.
Cold cathode vacuum tubes can easily survive 811 K with reserve
capability to survive 1000 K. Quartz melts at 1900 K.
Solid state transistors, mosfets and other circuitry on carbon/diamond
or just on quartz is also good to go as is.
Cooling or heat exchanging is also not an insurmountable problem.
