Right now AI can probably do the buying part, but seems to be absolutely no where near the curation part. Maybe that’s a good thing for humans, so I’m not too fussed.
Suppose you need to buy some stuff for an upcoming project or vacation, but don't want to go down a research rabbit hole for the next hour(s) to cure your ignorance. Suppose you don't even want to have a conversation with the AI. You just want it to build a shopping cart. At most, hopefully, your effort is just pruning the cart before placing the order (if even that).
I'm not saying AI wouldn't be corrupted like human customer service. I'm saying that we're actually pretty close to this already on Amazon with their AI, but not all ecommerce can be or has to be Amazon.
So now we have AI to overcome the hostile sellers, but the fact the sellers introduced the friction in the first place strongly suggests it will just come back again in some other form. It wasn't there by accident, it was serving people's interests and once AI vendors have finished getting consumers hooked in, they will then turn around and enshittify by giving the sellers back some of the friction - for a cut. So you won't be able to just order what you want without the "would you like fries with that?" or "what about this other brand?" coming back.
Guarantee they'll introduce some dynamic pricing shenanigans where they charge more when they identify that the shopper is an AI agent. Unsupervised AI with access to your credit card is basically the perfect target for price gouging.
They can pay the model provider, not amazon, but it would be less feasible because for now we have real competition among them.
History often rhimes but it doesn't always repeat itself.
I think there is genuinely a need for shopping agents and they could transform shopping in very good ways for the consumers.
Good thing for shoppers, bad for marketers, bad for people who relied on smarts, bad for margins, good for people who have capital and assets.
