Why don’t we see androids in the SW universe? Given Luke’s prosthetic hand, a life like android ought not to be a stretch. Is there a canonical reason?
I know at least one appeared in the old Marvel comic, which they went out of their way to say was non-sentient for some reason. And Valance the Hunter was able to conceal his half cybernetic face when it suited him.
That cyborgs were routinely discriminated against might be one factor against androids, but that could purely be a Marvel invention.

We know there are anti-droid sentiments held by some in the OT, but there are scenarios where an android might be useful on both sides of the conflict.
