I've skimmed over the article and much of it appears to be what was pounded into our (student) heads in college - it just took us time to start applying it.

Anyway, I have my own definition and it's "a person who realized that they've already forgotten stuff they used to know by heart in their junior years and approach every problem with appropriate humility stemming from said realization".

My "knowledge window" is, as I discovered, 9 years the skill that I've lost which established this was the ability to write an SQL statement - even a simple one.
