Human form or human function?
It is more efficient for humans to adapt to the Martian environment than to terraform Mars. Since history is determined by energy efficiency, unless alternatives emerge, robots and many cyborgs will primarily move to Mars in its early stages. The negative perception of cyborgs will change as society recognizes the contributions of people who embrace new human designs rather than clinging to evolved biological forms.
While the difference between biological and mechanical devices is overwhelming, we must not overlook the relative advantages of biological devices when transitioning to mechanical ones. Most leg functions can be virtualized, and sensory functions can be replaced with sensors. Even now, in actual factories, visual perception and decision-making are more common than manual labor. As production capacity is replaced, more people quit work due to surplus production rather than losing jobs.
Humanity will have limitations in development with humans as the minimum unit. These limitations will only change when that minimum unit changes or merges into one. The main difference between humans and animals is that humans can pass information to their offspring through non-genetic means. Furthermore, the difference from existing humanity will be even greater when sharing unified information remotely.
