The Marketing Department Has Left the Building

Nobody wants to say it out loud. So let's just say it.

There's a conversation happening in boardrooms and over coffee and in hushed Slack messages that nobody is quite willing to have in public yet. And it goes something like this: do we actually need all these people doing all this stuff?
Not in a cold, callous way. More in a genuinely confused, slightly panicked, slightly excited way.
I'm not here to hype AI, there's enough of that. But I spent years inside marketing departments, and when I look at what's happening right now, I'd be doing you a disservice if I dressed it up or softened it.
The work of a full marketing team: Strategy, Content, Research, Analytics, Brand, Customer intelligence - can now largely be done by AI. Not perfectly. Not without humans in the room. But substantially, and at a speed that makes the old way look almost quaint to me.
The annual strategy process used to kick off in Q4 and limp across the line sometime in January. I've lived it. We all have. That's weeks of workshops and decks and agency briefings for a document that AI can now draft — coherently, from your actual data — in two or three days.
That's not a prediction. That's what's happening right now, in businesses that have figured out how to use these tools properly.
The numbers, since we should probably look at those
I know how this can sound — like someone trying to sell you something, or scare you into something. So let's ground it in what the research actually says, because the data is pretty striking.
91% of marketers now actively use AI in their work — up from 63% last year
6.1hrs saved per marketer per week on average, according to HubSpot's 2026 report
23% of agencies have already cut junior copywriting headcount — 31% plan further cuts
And here's the one that really made me sit up: McKinsey is forecasting that AI systems will account for 40% of marketing spend by 2030, while human creative talent drops from 40% to 25%. That's not a fringe prediction. That's McKinsey.
The shift isn't coming. It's already well underway.
But here's what the hype pieces get wrong
Most writing about AI and marketing falls into one of two camps. Either breathless enthusiasm from people flogging courses, or defensive eye-rolling from agency folk protecting their patch. Neither is particularly useful.
The more honest picture is messier and more interesting than both.
Yes, AI can produce a month of social content in twenty minutes. Yes, it can synthesise competitor research that used to take two weeks. Yes, it can write your performance report and flag the anomalies before your analyst has even opened their laptop.
But 42% of companies abandoned most of their AI projects in 2025. Up from 17% the year before. Because buying tools is not the same as actually changing how you work. And a lot of businesses bought a lot of tools and then wondered why nothing changed.
What the research actually shows works
The organisations getting real returns from AI in marketing aren't the ones with the most tools. They're the ones who restructured around it — treating AI as the operating system, not a feature bolted on top. Smaller, more strategic teams. Humans making decisions, not pulling data. Senior thinking going up, production grunt work going to the machines.
That's a real change. And most businesses haven't made it yet.
The elephant, since we've come this far
Here's the thing nobody inside the industry says clearly: if AI can do the production work of a marketing team, the question of how many people you need — and what they should be doing — becomes genuinely open.
That's uncomfortable. It's uncomfortable for agencies. It's uncomfortable for in-house teams. It's uncomfortable for anyone whose job has historically been defined by doing the thing rather than deciding the thing.
What AI is bad at, and what remains entirely human: judgment, taste, the instinct that says this campaign is technically correct but it doesn't feel right, the relationship that gets you the front page, the strategic read that's three moves ahead of the data.
What AI has eliminated is the enormous amount of production work that used to sit underneath those skills. The grinding. The data-pulling. The first drafting. The stuff that was burning the best hours of talented people on work that was, let's be honest, fundamentally mechanical.
The marketing professionals who thrive from here are the ones who stop defining themselves by doing the work, and start defining themselves by knowing what work to do.
So what does this actually mean if you run a business?
It means the question isn't whether to use AI in your marketing. That ship has sailed — your competitors who are using it properly already have a structural advantage that compounds every month you wait.
The more useful question is: where does AI earn its keep fastest for a business like mine?
The marketing department as we knew it — the room full of people each owning a function, running slowly, producing in batches — that version is going. Not overnight. Not all at once. But it's going.
What replaces it is smaller, faster, more strategic, and built around people who understand how to direct AI rather than do everything themselves.
The businesses figuring that out now will look very different from their competitors in two years. That gap is the opportunity. And right now, in Ireland at least, most businesses haven't moved yet.
That window won't stay open forever.
