"Changing the world"

In Silicon Valley, you'll often hear someone voice the desire to "change the world". But what does that mean? If a person doesn't have some specific change in mind, together with careful thought on the effects of that change, then they are really just voicing a desire for notoriety. "I want to be famous" sounds a lot less noble than "I want to change the world", so they say the thing that sounds noble.

Making an impact on society is not virtuous in itself. An asteroid made an impact on the dinosaurs. Identifying the good takes hard work.

That's why so many "world-changers" found companies that make trivial apps. They don't actually want to work hard for a good cause. They want the easiest route to the fame that comes with making a quick buck.
