Thanks for posting that link; I had not seen that lecture before and found it highly enjoyable. For others that might gloss over a random link to youtube, this is a lecture from 2019 delivered by Jonathan Blow titled "Preventing the Collapse of Civilization." In this talk, he discusses the problem of generational transfer of knowledge within the historical context of civilizations who failed to do so successfully. At about the halfway point, he transitions to the related topic of declining software quality, which I suspect will resonate strongly with many programmers on this forum.
