In my opinion, humans have pushed centralization to the extremes, not technology per sé. We did it because centralization leads to more control and efficiency, things that humans love. I don't see the link between technology and patriarchy or racism, those existed long before the modern technology boom.
But I agree that we cannot use the centralization-hammer for everything. Funnily, technology is what will allow us to centralise less, so we can enjoy less control by the elite at the cost of a little, actually healthy, inefficiency.
