"Just because you can do something, doesn't mean you should." 

 That's how records are broken, how moons are stepped on, diseases are cured, by people who are willing to try. 

We call these people innovators. Fearless. Genius. We call them reckless. Thoughtless. Dangerous.

 It's hard to know which one we are. 

It's hard to know if what we're doing is just crazy or if it's going to change everything.
