According to the engineering comparison, which planet's surface might be *technically* easier to approach for minimal technology modification?

Answer

Mercury's surface

The text suggests that solving the extreme thermal gradient of Mercury (perhaps by sinking underground) might be an order of magnitude less challenging than building structures to resist the crushing pressure and incineration on Venus's surface.
