Unfortunately, people who have not experienced the joy of how well models work, have no clue how important they are. The GP may assume that "Advanced Technology" can get you to wherever you want. For Eg. he may look at a rocket engine and assume that you just need to start a powerful engine and keep steering your way to your destination as you would do in a car. He knows it is more complex that, but will probably never appreciate the fact that, if Newton's laws of motion or gravitation were off even by a small margin, we would never have achieved what we would have achieved. I hope more and more people realize that science and technology is more than just advanced or complicated.
