Alex Kantrowitz of the Big Technology newsletter has published a piece with a blunt warning for the industry: advertising is coming to AI, and nobody — users, platforms, or advertisers — is prepared for it.

The article, titled "Ads Are Coming to AI and None of Us Are Ready," comes from Big Technology, Kantrowitz's independent publication covering the major tech platforms.

That is the core of the available reporting: a headline, an author, and a warning. The syndicated feed Mart Signal received does not carry the full article text, so we are not going to invent the specifics — no revenue projections, no product names, no rollout dates that the source does not supply.

What we can say is this. The thesis itself matters. AI assistants and chat interfaces are absorbing attention that once went to search results and social feeds. Both of those surfaces monetized through advertising. The commercial logic of moving ads into conversational AI is straightforward, and a growing number of analysts expect it to happen.

Kantrowitz's framing — that none of us are ready — points at the unresolved questions. How do you place an ad inside a conversational answer without breaking user trust? Who audits the boundary between a helpful response and a paid one? What happens to publishers whose content trains or feeds these systems when the ad revenue lands elsewhere?

Those questions remain open. The full argument, with Kantrowitz's supporting detail, is in the original piece on Big Technology.

Mart Signal will follow up with concrete numbers, named products, and pricing as companies disclose their AI advertising plans. Until then, treat this one as a flag planted ahead of the rollout — not a launch report.
