Does Wikipedia count as a technical solution? I don't think the tech does anything without the people editing it. I believe it's the policy ("everyone can edit") that made the advancement, not the specific system they built to allow it. I agree on the second point, but it's more by accident in my opinion. If the technical solution leads to people finding it easier or cheaper to do something, they'll adopt it. Whether it's new, good, pristine, perfect, free & open etc, doesn't matter. It has to make their life easier, save them time and/or money or otherwise enhance the experience, that's what counts.
