My shower thought since I watched Star Trek: In a world where universal translators are ubiquitous, do babies even need to learn any common language, or do they each develop individual languages and let the UT handle the rest?
UT translating baby noises into articulate language, should have been in an episode.
It was Russia and other autocracies etc. that diminished the trust by actually financing developers for multiple years to first earn trust and finally introduce backdoors into open source software, as demonstrated by the XZ utils backdoor.
In open source projects, maintainers need to have some initial trust into each contributor, and let this trust naturally grow with time and contributions. They cannot perform intensive background checks on everyone before accepting a patch.
While it is easier to uncover backdoors in open source software, there is no good way to defend and prevent against this kind of attack in this type of development process. All open source projects can do is trying to take away some trust from people within higher risk groups. This of course might lead to discrimination.
