This is a deliberately obtuse reading of the author's intent. Read further:

> And not only have I written bad code. My friends have written bad code. My colleagues have written bad code. Our mentors have written bad code. The code that all of our code depends on was written by someone who wrote bad code. Bad code is everywhere.

The author's point is not that everyone writes bad code at some point, ever, which is trivially true as you pointed out. They're saying that our code is bad now, we just don't know it yet.

I like to say: Nobody will hate my code as much as myself in 6 months.
