Invent something besides free software, you mean? I think it can be sustainable if we can change the culture in tech so that it's normal to support open source. There are 20M programmers in the world. If 10% of us each had a budget of $1,000 from our employers to spend on open source each year, that would be $2B/yr for the open source community--equivalent to another Red Hat.
