For a very special meaning of "self-reliant". The majority of programmers I know could not produce their own food, make their own clothes, build their own shelter, treat their own illnesses. These are the fundamentals of life; how "self-reliant" can someone claim to be without being able to do these (I can't do these either, but I'm not claiming self-reliance)?
We can play into an illusion of "self-reliance" only because these foundations and so much more have been made so pervasive and efficient.
