Below are some of my favorite quotes by Alan Kay.
"Perspective is worth 80 IQ points."
"Some people worry that artificial intelligence will make us feel inferior, but then, anybody in his right mind should have an inferiority complex every time he looks at a flower."
"The best way to predict the future is to invent it."
"If you don't fail at least 90 percent of the time, you're not aiming high enough."
"People who are really serious about software should make their own hardware."
