One of the first things tourists notice in San Francisco these days is how many ads there are for terrible AI startups on billboards, on TV, and even on Muni bus stops. On the bright side, these Muni ads have become great canvases for street artists to share positive public messages. Like this “Free Muni!” poster, which used to be an ad for Delve AI. Or this “Humanity prevails” sign, which originally replaced a dystopian advertisement for a company called Dear World1. This Workato ad was modified to deliver a more worker-friendly message. And this final ad which used to be for an open source search tool. ¡Chinga la migra! I know the “Dear World” signs were supposed to be parodies, but in weird twist they were paid for to promote yet another AI startup, so… Still sucky. ↩︎
