AI Multiplies Advisor Expertise: A Computer Nerd Comes Clean

I am a nerd. I fell in love with the first computer I ever saw, in seventh grade (1971). It was an Educomp with a tape drive, and every instruction had to be entered via punch card, one card at a time, in exactly the right order, or nothing ran. Beyond a recurring fear that I'd drop my card stack while loading it into the feeder, I was all in.

Twelve years later, in 1983, I sat in front of an Apple IIe at Hoare Govett's Company Finance Department in London (my first job after college), looking at a blinking cursor and a crude program built to value convertible bonds. I asked the IT director whether I could make it more accurate. He laughingly told me to "go ahead" as he walked away. Two weeks later, the trading desk upstairs was pricing securities with my program.

In 2025, I wanted to understand our new investment models better than any off-the-shelf tool allowed, and I discovered new AI reasoning models could translate what I wanted into working code. That relationship has changed the economics of nearly everything my firm does today.

As much as we all hear that AI democratizes expertise, I see very directly how it does the opposite. The value of any AI interaction depends almost entirely on who is using it and how it is being directed. I maintain that the gap between how an expert and everyone else leverages these new tools has grown wider when any answer has to be judged rather than looked up.

What One Person Can Build

Since February 2026, I have been building FlightDeck, a market intelligence platform with live portfolio monitors, a market weather system, replays of historical crises, a regime classification history running back to 2000, and a publishing system for my firm’s research. It’s not a marketing site as much as an open kitchen where visitors can see the analysis and tools my colleagues and I use in our practice.

I am not a solo practitioner, but I am the chief engineer for our information systems as well as the chief portfolio and investment model designer. In other words, the Chief Nerd Officer speaks.

Compared with the way I would have developed this platform in 2019 (when I last undertook a large internet-driven project), it conservatively comes to the equivalent of roughly 3,800 hours of senior financial engineering. At the $150 to $200 an hour I would expect to pay experienced U.S. contract fintech engineers, that is well over half a million dollars before the first support ticket. Our actual cost was a handful of AI subscriptions, cloud hosting, and my design and engineering expertise in data fidelity across a site with many monitors and reporting modules.

That last item matters most: 40-plus years of knowing where data comes from, how it flows, and when a number is wrong is what made the design work. While everyone talks about democratization, the experts are getting “expertier.”

When I consider FlightDeck's impact on our business, the savings matter less than what it has unleashed for my team. Goodbye to committees! I can prototype in a well-focused afternoon what used to take months and far more money to test. Today, we cycle ideas far faster, because the feedback loop is shorter. Don’t blink — the fast got faster again.
