I disagree with you. There were plenty of ideas during the 1990s that were technically infeasible until further infrastructure upgrades allowed them to exist. Video streaming immediately comes to mind. It was unfathomable to have a video streaming service like Netflix exist in the 1990s. People would have ridiculed you, just as people ridicule some crypto ideas today. A modern example is video game streaming. Even 5 years ago, it was unfathomable that video game streaming high quality games was possible, and yet we are starting to see these services today.
