“The typical path of how people respond to life-changing inventions:

  1. I’ve never heard of it.
  2. I’ve heard of it but don’t understand it.
  3. I understand it, but I don’t see how it’s useful.
  4. I see how it could be fun for rich people, but not me.
  5. I use it, but it’s just a toy.
  6. It’s becoming more useful for me.
  7. I use it all the time.
  8. I could not imagine life without it.
  9. Seriously, people lived without it?
  10. It’s too powerful and needs to be regulated”
