We see versions but maybe there's a lifecycle to every medium. I m sure when TV was invented people made blue-sky predictions about how it would change the world for the better and not become the means that rich people use to rule over democratic audiences. The internet we know was the medium of one-to-all communication but it seems we -very soon- stumbled on the limits of such communication with all the censorship & tracking . Maybe the next medium will use some other mode, where one-to-all does not matter anymore

And while the internet changed societies, it did not "change societies", as in the western world democracies function pretty much as they did in the 80s, but with digital tools instead of analog. We did not see huge changes like when printing was invented: The world map is still the same
