Of course I trust my kids to make the most of the environment they are given, and given that their environment will differ from the one I am adapted for, they will likely surpass me in being well adapted to the environment of the future; it's still my responsibility to prepare them as best as I can for it.

You might put a baby in a pool so it can learn to swim, but you make sure their environment is such that drowning is an impossibility. A child destined to be an Olympian swimmer still requires guidance, even if their natural ability and inclinations outpace both their peers and their elders.

Yeah, I think there are environmental things for which our culture cannot prepare us, yet I also think many of our inherited behaviors and beliefs will help us because the environment may not change that much.
