The wording of this blog post is very silly, but I think there's a valid point in here, and that is: the right full-time job can still enable you to work on your startup.

That job probably isn't at Google though. There are lots of software engineering positions where hours are 9-5, the problems you solve aren't very hard and thus leave you with lots of mental energy, and there isn't much in terms of "extracurriculars" (conferences, etc) to occupy your time. These are terrible jobs if they're your only path for professional development, but they can be good for a 3-12 month stint while you try and get your startup off the ground. Low commitment, low stress, just enough to pay the bills and get you some health insurance.

I can't imagine a software position at Google ever matching that description though.
