The nice thing is that we got plenty of time to study Venus since we do not really even need to terraform Venus to colonise it in the short term. At a high enough altitude, both the pressure and temperature drops to Earth's equivilent. If you have a large enough structure that is relatively airtight (it doesn't need to be perfect), you only need a small temperature gradient to keep it aloft in the upper Venusuean atmosphere. You could have cloud cities with open air balcony areas where you can walk around with only some basic protective gear and an oxygen supply to protect against the corrosive air and perhaps enjoy gliders or other airborne amusements. It's also good practice for when we decide to attempt something similar with Saturn and some of the other gas giants.
