I disagree that there's a technological solution to late stage capitalism and the slow death of liberal democracy.
New technology doesn't change anything about social institutions - the most powerful groups before the technology was invented simply own the technology after it's invented and use it to further cement their power.
I think the luddites were on to something. We don't need technology, we need humans doing things a little differently, maybe even doing bizarre things like setting factories on fire. Personally I hope we can try other things before setting factories on fire, see Keith McHenry's version of The Anarchist Cookbook for peaceful resistance solutions as well.
The point is though without a restructure, new technology doesn't liberate, in fact it further entrenches existing power structures.
> New technology doesn't change anything about social institutions
This is of course demonstrably untrue. Marshall McLuhan devoted his life to illuminating how technology changes society. The printing press, radio, television and the Internet have all undoubtedly changed our social institutions. It's hard to imagine secular democracy ever becoming a thing if we hadn't been able to mass produce books and newspapers, and writing manuscripts had remained mostly under the control of the Church. It seems less probable that the Nazis would have come to power if not for the immense skill Goebbels and Hitler had in the use of radio. And I doubt Trump would have been elected if he hadn't known how to press people's buttons so well on social media.
Let's not forget that more ancient things like fire, agriculture and accounting are also technology that irrevocably changed humanity and put new people in power. Or take a look at how railroads remade American society. Or how sufficiently advanced sailboats placed half the world under the thrall of colonialism...
Absolutely there can exist technologies which are anti-democracy, and surveillance technologies are exactly that. You become afraid to say or write the wrong thing in public, and then to say or write it in private, and then to even think it, and finally the thing is forgotten. I felt like Orwell made the point well enough in 1984.
All that said I don't see technology saving us from our current problems, it needs to be invented, it needs to mature, there needs to be adoption. One might imagine mesh networking and censorship proof distributed messaging or something having an influence on society but we simply aren't there yet.
