I like the plan to have robots build a very tall mountain platform on Venus that would allow us to walk around outside on another planet, in a t-shirt and jeans (and a respirator, as you mentioned).

You could probably even grow plants on this mountain top.

After the base is established, we could start trying to terraform the atmosphere to make more of Venus inhabitable.

It's crazy to think that high-altitude Venus is more hospitable to us in many ways than is Antartica.

The mountains aren't tall enough, unfortunately. The highest peaks reach about 10 km above the mean radius, while the "nice" part of the atmosphere is 50-ish km up.
