"Reflections on trusting trust" is specifically called out as a motivation for the Bootstrappable Builds project[0], which I think is an interesting approach at regaining some of the trust in our software. Another, better known project is the work on Reproducible Builds[1], and of course it would be nice to have auditable hardware based on clearly documented designs.
