Today's Dark Line

AI is simultaneously generating two bills: a $30,000 unexpected bill on AWS and a $5.7 trillion market cap high on Wall Street. The former reminds us of the costs of out-of-control AI triggers, while the latter is the market's collective bet that "AI will never burst." Meanwhile, the academic community begins banning LLM-generated papers, and the education system experiences a flood of A grades due to ChatGPT—technology is navigating between chaos and bubble, while regulation, the market, and academia are each looking for new balance points on their respective battlefields. Every piece of news today is a footnote to this tremendous change.
