There’s a lot of hype right now about agentic buying the idea that AI agents will soon buy from other agents, automating entire decisions on our behalf. In theory, your AI talks to my AI, they compare specs, negotiate price, and everyone saves time.
That sounds efficient.
But here’s the tension: buying, as well as selling and marketing, have never just been about efficiency. They’ve always been about changing perspective.
The Myth of Purely Rational Decisions
On paper, B2B buying looks like the most logical process in the world:
features → specs → pricing → vendor chosen. But in reality, it’s way messier. Decisions are made by buying committees, not algorithms. And committees are made of people, with careers, reputations, fears, and risk tolerance.
A startup may have the perfect product. But if you’re a multi-billion-dollar public company, you’ll probably still choose the category leader. Not because it’s better, but because it’s safer. If something goes wrong with the market leader, you can say, “Everyone uses them.” If something goes wrong with the unknown startup you personally picked, everyone looks at you. That’s not logic. That’s emotion + risk management.
Automation Handles Transactions. Humans Shape Meaning.
Agentic AI will absolutely change the low-value, rules-based part of buying. “Order the toilet paper I like when it drops below a certain price and it has been more than X time from last time we bought it.” That’s not an AI revolution. That’s the automation we’ve had for years.
But AI can’t automate why someone falls in love with one brand over another. It can’t explain why a diamond ring is “I love you,” not “compressed carbon.” It can’t replicate why a bag or a pair of shoes feels like confidence, not leather.
Value is rarely intrinsic. It’s perceived. And perception is shaped, not by data, but by framing.
Even in B2B, Emotion Wins
IBM didn’t just sell enterprise hardware. They became the safe choice, the brand behind the line “Nobody ever got fired for buying IBM.” That was not a spec sheet. That was reputation insurance.
Workday didn’t run a Super Bowl ad explaining HR software features. They brought in real rock legends like Ozzy Osbourne, Joan Jett, and Paul Stanley
to remind executives that calling someone a “rock star” should actually mean something. They were not selling software. They were selling status and identity.
Volvo Trucks didn’t advertise engine output or steel composition. They suspended a full-size truck 65 feet in the air from a crane hook, with the President of Volvo Trucks standing on top of it, to prove the strength of a single towing pin. They turned a technical detail into a public dare: “Do you trust us now?” The product was functional. The story was emotional.
The Real Shift Ahead
Agentic AI will reshape how we search, shortlist, compare, and reorder. But it won’t remove the moment where someone needs to believe. It won’t remove the risk conversation, the identity conversation, or the “what will this mean for me?” moment. Automation can reduce friction. Only persuasion can create conviction.
The Bottom Line
AI may buy and AI may optimize. But the reason someone chooses, pays more, trusts, advocates, renews, or switches is because we still live in a world of perception, emotion, and belief. The part of business that is still profoundly human. And as long as that’s true, automation won’t replace marketing. It will just make the human part of marketing more valuable than ever.
