The short answer
No, AI won't make marketing textbooks obsolete. It will only make obsolete the ones that teach you to operate a specific tool. The principles – measure what works, give the customer one clear reason, know them and get their attention – are almost a hundred years old, and with AI they matter even more. AI can produce ten ads in a minute. It won't tell you which one to run. Only someone who knows the fundamentals can.
What AI really changes (and where the critics are right)
To be fair, the critics have a point. Working with AI should be in every curriculum today. Routine tasks that used to take hours – copy variations, campaign reports, first drafts of visuals – now take AI minutes. Anyone who doesn't learn this will be slower and more expensive than the competition. And yes, some specializations will change beyond recognition.
But speed isn't direction. And that's where the problem starts.
Four principles AI hasn't erased
1. Measure what works (Claude Hopkins, 1923)
Claude Hopkins worked for the advertising agency Lord & Thomas, and in 1923 he published Scientific Advertising. In it, he pushed for something we now take for granted: advertising should be tested. He put coupons in his ads so he'd know exactly which copy and which newspaper brought in customers.
Today, with AI: A/B tests, conversion tracking, attribution. AI can test hundreds of variations at once. But what to measure, and what counts as success (likes, leads or revenue?), still has to be decided by a person.
In a small business: a hairdresser puts two different discount codes on her flyer and her Instagram post. A month later she knows which one brought in clients. Hopkins would approve.
2. Give the customer one reason (Rosser Reeves, 1961)
Rosser Reeves of the New York agency Ted Bates described the unique selling proposition, or USP, in his book Reality in Advertising (1961): one clear reason to buy this product and not another. His most famous example is one everybody knows: M&M's "melts in your mouth, not in your hand."
Today, with AI: AI will generate twenty slogans in a second. But if you don't know what that one reason is, you're choosing blind. That's why in my article on AI social media managers I recommended a five-minute test: write one sentence on why a customer should pick you. That's Reeves's USP, 65 years later.
In a small business: a bakery doesn't have "the best cakes." It has "cakes made with butter from the farm in the next village." That's a reason a customer remembers.
3. Know your customer (David Ogilvy, 1963)
David Ogilvy, founder of one of Madison Avenue's best-known agencies, wrote a line in Confessions of an Advertising Man (1963) that generations of marketers still remember: "The consumer isn't a moron; she is your wife." In other words: don't underestimate the people you sell to, and get to know them.
Today, with AI: AI can personalize an email for every single customer. But personalization without understanding is just spam with a first name. Data tells you what people do. You only find out why by talking to them.
In a small business: after every job, a carpenter asks: "Why did you choose us?" After ten answers, he knows more about his customers than any AI analysis could tell him.
4. Stand out, or stay invisible (Bill Bernbach, 1959)
In 1959, the agency Doyle Dane Bernbach created the Think Small campaign for Volkswagen: a tiny car on a big empty page and self-deprecating copy, at a time when America loved giant cars. In 1999, Advertising Age named it the best advertising campaign of the 20th century. Bernbach knew that an ad that looks like everyone else's is money thrown away.
Today, with AI: this is where AI is weakest. It's built to produce probable – which means average – content. The survey of 100 companies I covered last time found that AI-written posts get less than half the likes of posts written by a person, on average. Bernbach had a word for that: invisible.
In a small business: instead of "Fall special, book now!", a hairdresser posts "I colored 214 heads this year. This one was the hardest." with a photo. No AI can come up with that for her, because only she knows the story.
Beware of one myth
"Madison Avenue" is shorthand, not an exact address. Hopkins worked in Chicago, not New York. And the famous 4Ps model (product, price, place, promotion) didn't come from an agency but from an academic textbook by E. Jerome McCarthy in 1960. Strictly speaking, we should say "the 20th-century American advertising school." It doesn't change the principles.
What students (and business owners) should learn today
My answer to the question on LinkedIn: both. The fundamentals and AI side by side, not one instead of the other. People who only know the tools will produce average work cheaply and fast. People who only know the theory will be slow. The ones who know both will win.
Five books I'd give to students and every business owner:
| Book | Author and year | What you get from it |
|---|
| Scientific Advertising | Claude Hopkins, 1923 | Test and measure, don't guess |
| Reality in Advertising | Rosser Reeves, 1961 | One clear reason to buy |
| Positioning | Al Ries and Jack Trout, 1981 | How to own a place in the customer's mind |
| Ogilvy on Advertising | David Ogilvy, 1983 | The craft of advertising, from copy to research |
| How Brands Grow | Byron Sharp, 2010 | How brands actually grow, based on data |
Then add one semester – or, for a business owner, one weekend – of AI: how to write a good brief, how to connect AI to your own data, and how to check its output. That last part is called "human in the loop." And checking the output is exactly what you need those books for.
Expert perspective: "AI can write you ten ads in a minute. It won't tell you which one to run. Only someone who understands positioning, knows their customer and knows why that customer should pick them can make that call. Channels change every few years; principles haven't changed in almost a century. If you want to understand what's happening now, you need a bit of humility and a return to the roots," says Michal Krčmář, founder of Don Marketer and a CMO with nearly two decades of experience in global marketing.
What to take away from this
AI is the most powerful marketing tool that has ever existed. But it's a tool. Measuring what works, giving the customer one clear reason, knowing them and getting their attention – AI has no answers to those questions; it just generates options faster. If you know the fundamentals, AI is your turbo. If you don't, it's a faster road to average.
Our calculator shows you how much to put into marketing and how to split your budget between brand building and sales activation. In other words, exactly what Hopkins and Bernbach were asking – just in dollars. Try it – it takes two minutes.
