Clark's laws

In "Profiles of the Future: An Inquiry into the Limits of the Possible", Arthur C. Clarke describes these 3 laws that are relevant wrt foresight research:

"
  1. 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.
  2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
  3. Any sufficiently advanced technology is indistinguishable from magic.

(...) As three laws were good enough for Newton, I have modestly decided to stop there."

Why do I blog this? these very basic laws are interesting to understand Clarke's approach to writing science-fiction and what are the underlying traits of his prognostications. Although, it's sci-fi, there is a lot to learn from his novels and these quotes act as valuables rules for foresight research; the implications of each of them would be good to discuss.
