Electricity was invented in the 1880s, but most factories did not see a real productivity jump from it until the 1920s. The technology was ready for decades before businesses redesigned their work around it. AI is moving faster than that, but it is following the same uneven path — and where your industry sits on that path is one of the more useful things you can know right now.
It's an S-curve, not a switch
Technologies spread slowly at first, then quickly through the middle, then slowly again as the last holdouts come along. Right now AI is somewhere in the steep middle for knowledge work — drafting, research, analysis, customer communication — and barely starting for physical, heavily regulated, or relationship-driven work. The cost and difficulty of adopting depends heavily on what you actually do, not just on how good the models have gotten.
The middle of the curve is the risky stretch
Being early is expensive — you pay to figure things out before there are good playbooks. Being late is also expensive, because by then competitors have priced their faster, cheaper operations into the market and customers expect it. The cheapest time to move is the early-middle: tools are mature enough to work, but the advantage is not yet table stakes. For most professional-service and office-heavy SMBs, that is exactly where AI is today.
Your industry's rate is not your rate
Averages hide the opportunity. If only a third of firms in your field use AI seriously, the average looks unimpressive — but that gap is the point. You do not have to beat the leaders; you have to beat the two-thirds standing still. Pick one workflow where your competitors are slow and you hold data they don't, and that is where adoption pays first.
The honest caveat
Diffusion curves are clearer in hindsight than in the moment. Nobody can tell you precisely where the steep part ends. Treat the curve as a way to ask a better question — "is this capability common yet in my field, or still rare?" — not as a forecast you can set a calendar by.
Start here: name the one task in your business where being six months ahead of your competition would actually show up in revenue or margin. That task is where the diffusion curve is working for you instead of against you.
