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.
...because our entire universe works on probabilities, there is a random bases along the constant of our universe, a combination of the two.
Also based on this probability, we as conscious beings can create alternatives possibilities, both from the past, we can create a new future in our forecasts (inside our minds) therefore creating time itself as it's only real since we're around to perceive it. There's a good video about it that I enjoyed it.
