The surface is no good but the atmosphere has layers of cool shit. Heat rises so floating something to occupy the band of atmosphere that is totally okay for humans isnt all that far fetched. It's still basically science fiction but harder science fiction than colonizing mars. Cloud cities on Venus sound more fantastic but are genuinely more likely than dome cities or whatever on Mars. There is a good amount of nitrogen and oxygen on Venus which is pretty useful the upper atmosphere does a solid job of producing oxygen out of the massive amounts of co2 in the atmosphere via photolysis. Keeping something going energy wise would be easy as well cause the planet is hot af, just hang a turbine and let the rising 'air' handle the rest. They're both silly sci fi ideas for now, but Venus is the better target to work towards as far as planets go. We are so fsr from ready for other planets that this is a measure of less impractical vs more impractical, we cant do either rn. Space stations are the way to go at the moment.
