You might have heard Clarke's Three Laws:
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Any sufficiently advanced technology is indistinguishable from magic.
Science fiction authors think more about potential, convergence and social implications than they do about technical feasibility, which is why they lead Science.
And they don't predict the future. Instead, they reveal possibilities. They inspire. They make the future easy to see, touch, understand and experience - even before the technology exists.
Just like founders.
