Even if it is fake, when was it created?
Having been alive in 1954, I am aware of the state of technology of the time, and much more familiar with the early history of what followed, from 1960 through 1980. If the caption is fake, of necessity it must mimic the state of technology when the fake image was made, must reflect the assessment of technology that was current. It does not seem to be MAD Magazine material.
I recall literally dozens of such predictions in poplular magazines of the late 40s, 50s and 60s. Unfortunately, I did not have access to the highly technical journals where such predictions might have been made.
