I see some overlap, but I think it's more complex than that. If we conflate the two so easily they lose meaning. Certainly, some people have that experience under capitalism. I think there are systemic failures which lead to life experiences that are probably not all that different from some peoples' experiences in feudal society, both at the top and bottom of the hierarchy.

The more I think about it though, I'm not sure feudalism is the right analogy. Serfs had a purpose and were depended upon. In a society where AGI is in the hands of a few, it seems reasonable to believe that there wouldn't be a need for serfs at all. Labour would become utterly irrelevant. You'd have no lord to be bound to. You'd be unnecessary.

I imagine the transition there would be some brutal form of capitalism, but the destination would not be fuedalism. I don't think we have a historical analog for that hypoethical destination.
