Understand The Future Of Marketing By Studying Finance

There's a 40-year case study sitting right in front of us, and almost nobody's talking about it.

‍

Investing.

‍

The data on active fund management vs. passive index funds has been settled for decades. About 90% of actively managed funds underperform the S&P 500 over any 15-year stretch. Warren Buffett famously bet $1 million that a simple index fund would beat a basket of hedge funds over 10 years. He won. It wasn't close.

‍

So financial advisors went extinct, right?

‍

No. The industry is bigger than ever. And here's why: financial advisors don't really get paid to pick stocks. Most of them literally just buy index funds for their clients - the exact thing a robo-advisor could do for free.

‍

They get paid to stop you from panic-selling during a crash. To keep you from dumping your retirement into crypto because your brother-in-law said so. To sit across the table and say "I know it feels scary, but we're not touching anything."

‍

Knowing what to invest in was never the hard part. Behaving correctly when your portfolio drops 30%... that's the hard part. And no algorithm has solved that.

‍

I learned a version of this the painful way. We briefly built custom AI software for clients at one of my companies. Exciting, cutting-edge, high-margin. Then I had a realization: as OpenAI gets better, our business gets worse. We were competing with a trillion-dollar company staffed by the brightest minds on earth. So we pivoted to boring fundamentals: newsletters, email marketing, consistent execution. A done-for-you service that every business on earth needs.

‍

This is exactly what's happening in marketing right now. AI will commoditize the average work. Writing copy, building reports, generating ads - all of it gets cheaper and faster. Some unit economics shift. Some roles shrink.

‍

But clients will always pay a premium for two things: genuinely differentiated creative, and the human judgment that keeps them from chasing the wrong strategy. The marketer who actually understands their business, manages their expectations, and holds them accountable to a plan they want to abandon every other week.

‍

So when someone asks "how will AI affect marketing?" - don't guess. Look at what already happened in finance. The commodity work got automated. The advisors who just picked stocks got squeezed. And the ones who managed client psychology? They raised their fees.

‍

If the only value you provide is the deliverables, be nervous. But if your value is in the strategy, the relationship, the hand-holding through hard decisions? AI just made the easy stuff cheaper. Your premium got more valuable.
