I'm concerned innovations in LLMs will silently replace human expertise in unverifiable and bitrot ways ultimately leading to widespread decline in mastery in many fields and possibly the loss of ability to teach, mentor, or maintain incomes of actual subject matter experts gradually to a point where no human SMEs can be found for critical technology or research necessary for organized civilization. Brave New World-Idiocracy with such incapable people in it. I'm betting climate change will also get us with hypercanes and famine affecting billions roughly at the same time.
