Extrapolating future technology from current technology is known to be a flawed method, this has been known for hundreds of years now, maybe longer.

For example, in the 1920's they also extrapolated their current tech into the future. It showed people walking around with phonographs strapped to their hips, having just been dropped off by their personal blimps. Predicting the future is hard, but extrapolating the current state forwards is almost always wrong, and shows a huge failure of imagination.
