Absolutely! The "stages of grief" are just the stages of approaching a problem. Grief is just special because it is an unsolvable problem and so you go through all of the stages. Entering one or more stages of this process does not mean that you are going to go through all of them. In most non-grief cases it stops earlier.
Ideally, skepticism has none of that: Denial is arguably not part of skepticism - it lacks skepticism of yourself (i.e., denial includes certainty). Skeptics has nothing to do with anger, or bargaining (you can't negotiate truth); and depression and emotional acceptance also are out of place.
Skepticism is unemotional in that its definition doesn't reach into emotion. But skeptics - all humans, as far as we know - are emotional creatures, and beyond a doubt those emotions play a role in driving much skepticism.
Which returns me to my point: Many responses to AI are driven more by those emotions than by skepicism.
