Flipping rockets is a simpler problem in the sense that it the required technology already existed, there just wasn't anyone with enough incentive and resources to actually do it.

Human-level robotics, on the other hand, is not a problem of missing incentive. For all I know about the field (as a casual observer), we are still several breakthroughs away from achieving this goal.

How do you define the “required technology” for these problems?

We have actuators, sensors, and computers to build humanoid robots, isn’t it “just” a software problem like flipping rockets was?
