Robert Heinlein famously tried predicting the future and did a shockingly good job back in the ’50′s. For instance, he predicted cell phones.
Here’s what he believed would NOT likely ever come to pass.
Here are things we won’t get soon, if ever:
— Travel through time
— Travel faster than the speed of light
— “Radio” transmission of matter.
— Manlike robots with manlike reactions
— Laboratory creation of life
— Real understanding of what “thought” is and how it is related to matter.
— Scientific proof of personal survival after death.
— Nor a permanent end to war.
