Pew's detection of AI authorship across a third of recently published webpages shows the web's content ecosystem is now machine-generated by default. The issue is consumer trust: people shopping, researching, and reading can't reliably distinguish human expertise from synthetic filler, degrading signal-to-noise ratios when they need reliable information. The pressure isn't on detection tools but on platforms and publishers to either credibly certify human authorship or accept that content authenticity has become a competitive advantage.
