I agree that our more base traits seem to have survived from prehistoric times well into the present, but things like the exploratory drive seem to be redirected actually--yes, there is space exploration, and the technology is more advanced, but the accomplishments are arguably lesser: walking on the Moon vs. having a space station in low Earth orbit. And even if people were willing to make a one-way trip to colonize Mars--a trip perhaps of similar magnitude to our civilization as crossing the Atlantic was for Renaissance Europeans--there does not seem to be sustained initiative and funding from government to accomplish it. Even so, explorations are made, but they are largely being made inwardly, with computers in countless fields including math and medicine.
