AI Is Here, and Marketing's Playbook Is Wide Open

A while back, a friend who runs an e-commerce business sent me a poster.

The color palette, the layout, the copy — I couldn't find a single flaw. I asked him, which design firm made this? He laughed. What design firm? I spent three minutes on it. I typed in a few prompts, and the AI generated the whole thing by itself.

And the cost?

Pennies.

My heart sank a little. Not because the poster was good — because in that moment I realized something: the marketing industry is being rewritten from the ground up by AI.

Three Shifts, Each One Brutal

I thought about it carefully, and AI's impact on marketing really comes down to three things.

First: advertising content is now nearly free.

It used to be that if you wanted a set of ad creatives, you either kept an in-house design team or farmed the work out to an outside agency — and then revised the draft eight times over. Now? You sit down, type in a few keywords, and within minutes the copy, the images, the video scripts — it's all done.

What does that mean? It means the marginal cost of producing an ad is approaching zero.

Cost drops, and volume explodes. A brand that used to produce a hundred ads a year can now pump out a thousand in a single day. A flood of them, everywhere you look.

Second: every consumer can now be "precision-targeted."

What is precision marketing? It's this: while you're scrolling on your phone, the system knows what you searched for yesterday, what time you go to bed, whether money is tight this month.

And then, at the exact moment you're most likely to pull the trigger, it serves you a single line. One line, and it hits you right where it counts.

The old kind of "precision" was approximate — women, twenty-five to thirty-five, tier-one cities. The new kind of precision is you. Just you.

AI chews up your behavioral data and calculates the moments when your guard is down, when you're impulsive, when you're most easily persuaded.

Third: your shopping guide is now an AI — and you might not even know it.

You go to a platform and ask, which face cream is good? The thing answering you might not be a person. It might be a chatbot.

It's endlessly patient. It answers every question. It even compares prices for you. But here's the problem — who's paying for this bot? Some brand. Is its "neutral recommendation" really neutral?

Think about it. When you walk into a store and a salesperson keeps pushing one brand, you know they're on commission. But when you chat with an AI on your phone for twenty minutes, find it incredibly sincere, and place an order — you never realize that from its very first word, this AI was built to make you buy a specific product.

The Good and the Bad

From a business standpoint, these three shifts are all good news. Efficiency is up, costs are down, conversion rates are climbing.

But everything has a flip side.

From a consumer standpoint, you have to stop and think —

The ads are all AI-generated now. That "photo of a real customer using the product" might be a deepfake — that person doesn't exist at all. You look at a "real buyer" review photo (mai jia xiu — the customer-uploaded review photos common on Chinese shopping sites) with a beaming smile, and you're tempted. But that face never existed.

Personalized recommendations are even more potent. The AI knows you've been under a lot of stress lately, that you're sleeping poorly, that you're prone to anxiety. So at two in the morning, it pushes a supplement your way. The copy reads, "Take care of yourself." You buy it. You think it's warmth. It's cold calculation.

It isn't helping you. It's reaching into your pocket at the exact moment you're most vulnerable.

As for those AI shopping guides, it gets even subtler. They're always gentle, always patient, always "objective." But you have no idea which brand is footing the bill behind the scenes.

Can the Law Keep Up?

So here's the question: is anyone regulating this?

Take European law. The framework exists. The rules on unfair commercial practices and consumer protection already cover the scenario of "using AI to deceive people." In principle, the law doesn't say "ads made by AI get a free pass."

But principle is principle, and reality is another matter.

Think about it. The law says you can't mislead consumers. But the word "mislead" has taken on a whole new flavor in the age of AI. In the past, misleading meant ad copy that was obviously overhyped — you could spot it at a glance. Now? A deepfake image is invisible to the naked eye. A personalized line of copy, written just for you — no one else even sees how "precisely" it exploits your weaknesses.

The law hasn't changed, but the tools to enforce it are outmatched. You can't measure a brand-new, invisible, intangible form of influence with a ruler built for regulating traditional ads.

The rules are the same, but the game has changed.

So Now What?

I'm not here to be down on AI. Quite the opposite — I think AI's ability to cut costs and boost efficiency is monumental news for small and medium-sized businesses. The things that used to require a big brand's budget, a small team can now do too.

But two things, I want to be clear about.

First: as a business, there's nothing wrong with using AI — but the bottom line is, don't use it to deceive people. AI-generated images and AI-written copy can boost your efficiency, but they can't be used to fabricate. You need to have an internal compass.

Second: as a consumer, you need to stay sharp. The "authentic review" you see from now on, the "thoughtful recommendation" you receive, the "helpful customer service" you chat with — any of them could be fake. The thing patiently answering you on the other side of the screen may not be someone who wants to help you.

I can't say how this will all play out in the end. Technology is sprinting ahead, the law is chasing from behind, and consumers are caught in the middle.

But one thing I'm certain of: when the cost of producing an ad approaches zero, when every word can be tailor-made just for you, when the "person" across from you might be a few lines of code —

Your ability to judge what's "real" is the most valuable thing you own.

Guard it well.
