> Google might not need you to code some efficient algorithm to search a b-tree every day, but they pay top dollar and can rightly expect that their software engineers can come up with efficient and creative solutions to hard problems without dragging the rest of their team down.

But hey, that's fine—they just leave good talent for others to hire.
