Venus has an altitude 50km ish where the pressure is earth like and so is the temperature. Humans could build a floating bubble city and even go outside in chemsuits and SCBA like tanks the pressure temp is so close to earth its the toxic CO2 and sulfuric acid that needs to be shielded against. Buckminster fuller did the calculations that a 1000 meter wide spheres filled with air at that altitude would not only be a lifting gas the volume of said sphere of air is so large its lifting capacity is 700,000 tonnes you don’t even need carbon fiber, steel triangular supports in typical Buckminster dome config but spherical with double layer plastic envelope and hanging tension lines from the top done leaves hundreds of thousands of tonnes worth of a lift for habitat and floor space to grow things put a solid deck at the equator hung from above and use that for open spaces hang your habitat buildings below it in the shade and you have 500 meters worth of vertical space down there to hang all kinds of hab shapes. Back then they though they would need vast flat spaces to grow food that’s not the case now with artificial photosynthesis you can grow food in tanks via acetate made form CO2 and water. You need to bring water and nitrogen to Venus it has CO2 in excess. Your flat deck can be 1sq meter solar panels each one making 40 times the mass of food vs a square meter of crops grown. Acetate can also be feed to yeast or bacteria to make protein and lipids and carbs aka food. Venus is actually a much better target for human habitats if we cab master building and transporting kilometer sized collapsible structures or floating robotic assembly’s blimps that make a sphere from the top down using a balloon under it gradually filling it as the dome cross to sphere around its. Once fully spherical the ballon formes the inner wall and you attach an exterior one to the outside of the triangular support structure. Once both are in place you enter from the top and start hanging things downward until your deck is formed that’s your hard deck to build up and down from then on.

One stray micrometeorite can ruin your whole day ...
... and you are still on a planet closer to the Sun... If the Sun pops out a “skadoosh” type event, or as it starts it’s journey to red giant state, being CLOSER is not a good thing.
Short term? Sure... let’s do it. Venus, Mars, Titan, and anywhere else we can start, build, and develop a human habitat. Exploit ALL of the Systems resources whereever found and eventually figure out a way to get to other solar systems.
Will it take thousands of year? Sure... but what else are we going to do? Keep waching The View?
