To counter your example, I doubt people would go back to print encyclopedia once wikipedia were to be banned. Wikipedia has fundamentally changed the way one looks up reliable information online, with simple computer-enabled features such as searching, cross-referencing,fact-checking, etc. We would likely see people getting dumber (due to the lesser and scattered number of sources) or relying on less reliable internet sources for information. Or outright piracy, which is of zero utility to the publishers.

Ride sharing has fundamentally changed the way I travel in developing countries. It's much easier to rely on an app's set price rather than haggle with taxi drivers on offers far higher than Uber's. On the other hand, I have found less utility in developed countries where it's much easier (and cheaper in general) to rent/buy your own car, or rely on a cab meter. Likewise I don't really see people moving back to the old ways - on the contrary, a number of taxi companies and cities are already exploring/already begun app-based services.

Maybe a few years from now, we might see Star Alliance type industry groups within the taxi industry.
