Looking at the history of science, technology actually seems pretty good at disrupting and replacing the controlling class. The Renaissance led to the general irrelevancy of the hereditary nobility across most of Europe; the industrial revolution led to the irrelevance of the landed plantation class in the U.S. and the landed gentry in Europe. This is not just a matter of the leaders of the technology revolution being accepted into the existing aristocracy; instead, there's often a series of wars and revolutions where the controlling class of the new technology replaces and then subverts the controlling class of the old order, usually bringing their particular culture and class markers with it.

What technology can't do is get rid of power structures entirely. There will still be a controlling class. It just will be made up with different people.

There's actually evidence that people who were wealthy in pre-Rennaissance Florence are still wealthy today [1].

And in US plantations, the technological innovation of the "Cotton Gin" allowed existing plantation owners to expand and increase the use of slaves.

(I don't think these disprove your point, but there's a lot more going on with your specific examples than one would think)
