Dwarves will come back when the environment and the material world change.
I disagree with you about the AI because at the end they are only 0s and 1s who can simulate a lot of our functionalities, specially physical ones, but they lack the capability of replacing humans as they lack consciousness in the sense that we don't operate in binary, there is the quantum effect of the observation effect that create/observe reality. Maybe with quantum computing, things might change.

Maybe. Logically I came to the conclusion it is because if free will wasn't real, everything would be predetermined and randomness and alternative possibilities wouldn't be possible, including the capability of modeling futures and analyzing causal occurrence themselves through time and other dimensions.
Although we're still not able to prove it either way with our current technology/enlightenment level.
