This views education as something you get from your peers and/or from your employer. It's true, but incomplete. You also get education from challenges you face. In a startup, you'll be often challenged out of your comfort zone. This will force you to learn. If not from your peers, of which there may be none able to teach you, then from other sources. On the other side, in a big company, you'll be much more limited in your scope of action. You'll get very very good at tightening that specific model of screw.

It is a balance between models of learning, the best position is, as ever, in the middle.
