What is the first step? Surely you can't mean the author using open source software (which they might already), or writing new open-source software like they envision? In the face of the societal changes they are talking about, one person will accomplish nothing. So the first step must be writing about it, trying to convince other people, or maybe developing their ideas so that instead of just a goal, they have a reasonable mechanism to get there.

Or is that the actual first step to make a societal-level change? Maybe it's better to make millions of dollars under the existing regime, and then found or fund a think-tank to get certain politicians elected.
