None of that precludes replacing huge swathes of advertising content with generated content, though? I'm not sure I understand the relevance.

In fact, being able to produce unlimited numbers and variations and combinations of adverts and have them compete against each other in the real world and be scored on tiny deltas in metrics becomes much more possible if you can automate basically the whole process. But it's a multimillion spend if you have to recruit actual actors and actual film crews and actual food photographers or drone pilots and car drivers and location scouts and so on to film and edit just a handful of variants let alone thousands.

Maybe there will always be a creamy top layer of increasingly-expensive artisanal handmade advertising but I predict we will end up with a huge sloppy middle ground of generated advertising that is just there to flash bright colours, jingles, movement and brand names into your brain.

I'm not saying it will be good advertising, very much the opposite (not that I think most much non-AI advertising is "good", it's mostly repetitive crap) but I think it will be very cost effective.

Maybe it won't be as effective as "real" ads but it'll be a hell of a lot cheaper and getting 80% of the bang for 5% of the buck means you can do a lot more of it in more channels (or pocket the difference). Every penny you save is a penny you can use to bid for the better slots.
