What exactly do you mean by the term "Unicorns"?

In my mind, rare and mythic creatures (and their human analogs) cannot be trained into existence. Sure you can take a group of people and show them how to do something, but the result would be closer to a squad of foot-soldiers than a herd of Unicorns.

In The Valley, Unicorns are devs that also have some graphic design skills.

In other places, they are often devs that also have deep domain knowledge. Like an elevator repair tech who also codes, esp useful for your elevator repair startup.

Oh come on, you know you are kneejerking. That guy tries to built something valuable and is putting effort into teaching other people, and you are trying to argue some sort of mythology with him.

@OP: My suggestion would be to start with something you are really good with and start building a community from there. The "JavascriptIsSexy" blog/curriculum might be an example of an approach like that. What he does really good is combining existing tutorial/services (codecademy, books, etc), spot their weaknesses and offers guidance on how to overcome these towards a more rewarding learning experience. Another suggestion would be to take a look at the various (in-person) coding bootcamps and see what structure they are following.
