They are in the right space at the right time, they have the right image, and they are probably backed up by a hefty amount of good luck (and investment money) to boot. There are a million and one co-working spaces, I've spent a huge proportion of my professional life at one co-working space or another, in some form or another, certainly ever since they became a "thing", and my rule of thumb that has come out of all of this is that the fancier and more salubrious (and expensive) one is, the less likely one is to produce authentic or meaningful work (obviously according to my own personal definition of meaningful and assuming that authenticity is important to the worker).
