To emphasize this point, I point to a section in Code Complete. This stated that a number of studies have concluded that programmer skill is the largest factor in efficiency. Using identical problems, environments, languages, etc ... the best programmers were 10 times faster with roughly 80% fewer errors, the code was much more readable, and used about 50% less lines.

We are the carpenters and bricklayers of the Information Age.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
