For me I say this: I don't need to draw a line for other people.
If I choose to hire someone for a job, I really don't care how they got there. Be it self taught or through school or university.
Drawing a line always means you take away opportunity, which isn't yours to take.
What if you hire a firm to build you a 25-storey office tower? Do you care if the firm's structural engineer actually went to engineering school?
I sure do.
