You do realise theres easy push back for this?

Go back to the movies of 30-40 years ago... that's what people envisioned about the future.

Yes, but I believe (perhaps incorrectly) that the is easy push back for most things. My question stands, is this rate of change something that the commenter could foresee. If not; it sands to reason that we should not assume the next leaps would be something that we will naturally foresee.
