Manufacturing guy-at-large.

From an old essay:

A lot of startups worry "what if Google builds something like us?" Actually big companies are not the ones you have to worry about-- not even Google. The people at Google are smart, but no smarter than you; they're not as motivated, because Google is not going to go out of business if this one product fails.

I think that being smart barely enters the equation. Motivation, though, counts.
