Not exactly, if I am thinking of leaving my job and I have responsibilities, I will not even entertain taking a leap of faith, resigning from my current position and grinding for 3 month in a super-competitive environment for 1/10 of a chance of getting a better job.
I'll talk to recruiters and interview at other companies on my spare time, as before.
My point was that this perspective is not lost on the author of that article, as he directly addresses it.
