Actually, it's called, "Uzza".
The first colonies on Venus will probably be floating-cities in the upper-atmosphere, where it's comfortable for humans.
If you can terraform the atmosphere, all that CO2 can be separated into O2, and if you add hydrogen, you can make water; but, what to do with all that carbon? You need to eject it into space.
So, increase Venus' spin; so, poor Venus get hit and knocked upside-down during the Hadrian-epoch and being closer to the Sun, slowed it's rotation; but, if you increase the spin, you need a lot of power, a lot of power to move a planet so, that's going to generate heat. Venus doesn't need anymore heat.
One problem with terraforming Venus is we're trying to solve a future problem with current-technology. Can't we use HPG and just gate the atmosphere, to some other system?
And can't we use all that carbon from the CO2 in orbital-manufacturing? Could you not have a viable orbital-shipyards around Venus?
But in the end, you need Venus to have a high-rotation-rate to turn on Uzza's magnetic-field. But, in the end, humanity is going to bollocks that up; so, a 31st century Venus will be:
Have a five-hour day (whoops).
Be about 50% Oxygen
Atmospheric-pressure is still high, maybe still be very hot, but the air-pressure is high enough for liquid-water.
Have a low amount of water on the surface; the only why to get hydrogen is from the stellar-wind and then combine it with O2.
It would be awesome for photosynthesis, so, plants may have to be in greenhouses (trap the water), or genetically modified.
