Today's dark line
AI is simultaneously generating two kinds of bills: a $30,000 unexpected invoice on AWS, and a new all-time market capitalization high of $5.7 trillion on Wall Street. The former reminds us of the cost of uncontrolled AI usage, while the latter reflects the market’s collective bet on “AI never crashes.” Meanwhile, academia is beginning to ban LLM-generated papers, and educational systems are seeing an epidemic of A grades due to ChatGPT—technology teeters between runaway growth and speculation, while regulators, markets, and academic circles each seek new equilibrium on their own frontlines. Every headline today is a footnote to this massive transformation.
