Today’s Underlying Thread

AI is simultaneously creating two kinds of bills: a $30k unexpected bill on AWS, and a $5.7 trillion market cap high on Wall Street. The former reminds us of the cost of out-of-control AI calls, the latter is the market’s collective bet on “AI never collapses.” Meanwhile, academia begins banning LLM-generated papers, education systems see A scores everywhere due to ChatGPT—technology swings between out of control and bubble, while regulators, markets, and academia seek new balances on their respective battlegrounds. Every piece of today’s news is a footnote to this great upheaval.
