LOL, this is madness. Move fast and forget everything:
In the March 2022 hearing, Zarashaw and Steven Elia, a software engineering manager, described Facebook as a data-processing apparatus so complex that it defies understanding from within. The hearing amounted to two high-ranking engineers at one of the most powerful and resource-flush engineering outfits in history describing their product as an unknowable machine. […] The fundamental problem, according to the engineers in the hearing, is that […] the company never bothered to cultivate institutional knowledge of how each of these component systems works, what they do, or who’s using them.
