I was replying to your comment about open source development. Bootstrapping is always a viable execution path, never said otherwise. My point was there is a crucible by having accountability to others that is not the same as a volunteer software project.
You also don’t get any reward, potential or tangible, even if you happened to have built the most important software project the world have ever seen.
