What interesting times to live through! "If someone can teach you how to do something, it's already mainstream." I don't think collaborative learning should be undervalued, though. There are several colleagues without whose example and input I would be a much worse programmer. Not in technical details, but harder to define things, like attitude that leads to success and how to make designs simpler. 'Mainstream' does not mean obsolete. Reading and writing and Roman alphabet have been mainstream for centuries, yet people utilize them with an amazing variance of productivity and value.
