Afraid not. The "good" programmers/engineers/whathaveyou are, more often that not, the ones that proverbially "live and breathe" their craft, and have done so for a very large amount of, how should I say, "units of actual work-effort." Pulling all-nighters on personal projects just for the fun of it, constantly learning and improving for the sheer bliss of the challenge and seeking of knowledge, these are the "good" programmers. They are putting in concentrated, heavy effort, which is far in excess of a mere 40-hours of unfocused, drone-tier non-effort per week. It is also why there are teenagers who can sprint circles around big-corporate code monkeys sporting 35 years of "experience."
Yes 20 years, but the majority of developers don't have anything remotely close to that many years in the field.
I've worked with many developers over my career and the ones who do programming on weekends and off-hours tended to produce significant more output than those who didn't.
Anybody who puts any effort to improve themselves and skillsets by working off-hours means they're rising above mediocracy.
^This. First Slashdot, then Ars, now HN filled with an ever-increasing amount of mediocrity. But, I passed bootcamp! I have more structured hours of experience sleeping at my desk and slacking off in the nap room -- that makes me a better programmer, I promise! If it wasn't covered in a test or in my assignments, it doesn't exist! The Office Space meme has come full circle, two decades later.
This is very elitist and not true. 40 hours a week for 20 years is more than enough to be considered “good” at the very least.
