From someone who has the opposite view, that human consciousness did not arise from an evolutionary process, but was created by God -- I believe we will never fully create an artificial consciousness.
I think a further assumption is that the human mind is a deterministic machine. If we could freeze whatever entropy is involved with human behavior, just like the seed of a Minecraft world, we could get the same result, and perhaps even control human behavior.
I don't think consciousness is deterministic like that. I have some things I can point to for justification, but much more largely, there are some strange implications that arise from "we're all dancing to our DNA".
Anyways.
