Science Fiction is based entirely on WHAT IF. Aren't all inventions based on WHAT IF? Some say some say that asking "WHAT IF" is invalid. I say they don't understand what they are saying nor do they have any vision or creativity or sense of what it takes to make "advances".
WHAT IF I were to try this? WHAT IF I were to redesign this? WHAT IF this could cut cost by 50%? WHAT IF this could change the way we all live for the better?
WHAT IF we had never WHAT IFFED? Well there would be no computers of cellphone or telephones or radios or or automobiles. For starters. Those who ask WHAT IF may not be the creators thereof but they are often the catalyst for others to ask WHAT IF and then find out by doing and trying and investigating and researching and doing something about it.
My opinion of course. What's yours? Would YOU prefer a world without WHAT IF?
