In 1937, a Texas school exploded because natural gas has no smell — nobody could detect the leak until it killed nearly 300 people, most of them children. Within weeks, Texas passed the first law forcing gas companies to add an odor. That fix, mercaptan, is still the reason your kitchen reeks of rotten eggs during a leak today. It didn’t change the product. It just made an invisible danger detectable — and only because regulators forced the industry’s hand.
That’s the history behind this week’s AI news. On August 2nd, the EU AI Act’s transparency rules took effect, requiring any company serving EU users to make AI-generated content detectable — or face a fine of €15 million or 3% of worldwide revenue, whichever is larger. Google and OpenAI committed to compliance back in May. This week Anthropic followed, saying it will embed statistical watermarks in AI-generated text and use C2PA provenance standards for images. None of them have shipped a public tool that lets you or me actually check the mark yet — the additive is in the gas, but we can’t smell it.
The bigger question is whether it’s already too late. One widely cited study found nearly half of new articles online are now AI-generated — though a follow-up from the same firm found human-written work still dominates what Google actually surfaces in search. I dig into what that split might mean, and why the social embarrassment of getting “outed” by a watermark might do more to change our behavior than the regulation itself.
