There's a quiet truth about AI productivity that nobody in the rollout business wants to say out loud: most of the people using AI today aren't actually using it well. They've adopted the surface — they ask questions, they get answers, they paste — and they've stalled there. The economic gap isn't between people who use AI and people who don't. It's between people who use AI as a chatbot and people who use it as a working partner.
That gap is the entire reason Lucy exists. To make sense of it, you need a clearer picture of what "using AI well" actually looks like at different levels. So here's the model we work from.
The four rungs
We map AI capability across four rungs. Each one represents a different relationship with AI, a different kind of work the human does, and a different kind of value that comes back. The transitions between them are not automatic. They require coaching.
Rung 1 — Chatbot
You use AI like Google. You ask it questions. You paste in a paragraph and ask for a summary. You generate a draft email and tweak it. You don't have a system. You have moments.
This is where most people stop. Not because they can't go further, but because nobody has shown them what "further" looks like. The thousands of online courses and YouTube tutorials trying to drag people from rung 1 to rung 2 mostly fail — because they teach concepts in the abstract, in a classroom, on someone else's example. By the time you sit down to your own work, the technique is gone.
The value at rung 1 is real but small. You save fifteen minutes here, twenty minutes there. You feel slightly better about your tools. You don't change your day.
Rung 2 — Working with AI
This is the rung where most of the economic value lives. And almost everyone overlooks it.
At rung 2, you've internalized the universal capabilities that turn AI from a curiosity into a working partner. You know how to write a prompt that gets useful output the first time. You know how to iterate when it doesn't. You can tell when the AI is hallucinating versus when it's right. You know which tool to reach for when. You know how to give the AI enough context for it to actually help you.
The research backs this up. The Brynjolfsson, Li, and Raymond NBER study of customer-service workers using generative AI found a 14% productivity gain on average — but a 34% gain for less-experienced workers. Why? Because the universal capabilities of working with AI are exactly the leverage point that lifts the people who needed it most. Not the model. The technique.
Lucy Labs' competency framework decomposes this layer into ten universal capability areas, weighted by how much of the actual day-to-day work they cover. The top five — prompting fundamentals, effective iteration, output evaluation, context management, and AI-aware task decomposition — account for roughly 68% of total competency. These are the skills that move you from "AI is a thing I sometimes use" to "AI is a thing I work with."
Most people will stop here. And honestly, this is enough. If your entire team gets to rung 2, your business gets a productivity bump that compounds quietly across every workflow. You don't need everyone to be a builder. You need everyone to be working with AI well.
Rung 3 — Domain expert with AI
At rung 3, the universal capabilities meet your specific work. AI stops being a generic chatbot and starts being a tool that fits your job.
If you're in sales, this is when AI starts handling the parts of customer prep that used to eat your morning. If you're an engineer, this is Cursor or Copilot in your editor, suggesting what you'd have written in half the time. If you're an analyst, this is natural-language data exploration with ChatGPT Advanced Analysis instead of staring at SQL. If you're in marketing, this is multimodal creation that compresses days of design iteration into hours.
We map this layer across six specialized domains: code generation, agent building and automation, presentation design, visual content creation, research synthesis, and data analysis prompting. Each one builds on the universal capabilities at rung 2 — and each one lets a domain expert outpace the generic AI user dramatically. This is where the differentiated economic value shows up. The 95th-percentile salesperson doesn't just sell more — they prep faster, follow up sharper, and never miss the nuance from the meeting that closes the deal.
You don't need to reach every domain. You only need to reach the ones that match your actual work. The 70/30 model: roughly 70% of your value comes from the universal capabilities at rung 2, and 30% comes from the specialized capabilities at rung 3, applied just-in-time as your work demands them.
Rung 4 — Solution builder
At rung 4, you stop using AI tools and start building them.
This is the rung where you notice the same forty-five-minute task happening every Wednesday and you build an agent that handles it for you. Where you walk out of a customer meeting and your follow-up draft is already in your inbox by the time you reach your desk. Where the spreadsheet you used to maintain by hand becomes a workflow that runs on its own. Where your hard-won pattern stops dying in your head and starts working for the rest of your team.
This is also the rung where the math gets dramatic. A single solution built at rung 4 can save hundreds of hours per year and replace a SaaS subscription that didn't quite fit. A team of solution builders can rebuild how a department operates, fast, without waiting six months for IT to deploy a new vendor.
And here's the honest part: somewhere between 10 and 20 percent of people will ever get to rung 4. That's not a problem. It's the model. Not everyone wants to build. Not everyone has the bandwidth. But the people who do reach rung 4 generate compounding value for the organization — and they tend to be the people who would have been your highest-leverage employees regardless. Lucy doesn't try to drag everyone to rung 4. Lucy makes the climb available to anyone who wants it, with coaching that meets them in their actual work.
Why most rollouts skip past rung 2
The conventional AI rollout playbook is built around two beats: "give people the tools" (rung 1) and "show them what's possible" (a glimpse of rung 4 in a vendor demo). The middle — rung 2 and rung 3 — is treated as something that "just happens" once people see the tools.
It doesn't. The middle is where coaching matters most, where almost no rollout invests, and where the actual capability is built. Companies spend billions on AI tools and consulting and training, and the middle stays empty.
Lucy Labs exists to fill that middle. Not by running another training course. Not by deploying another tool. By coaching people in the moment, on their actual work, until the universal capabilities at rung 2 become muscle memory — and then making the next rungs available for the people who want to climb.
What this means for you
If you're an individual reading this: figure out which rung you're on. Be honest. Most people overestimate themselves by half a rung. Then ask yourself which rung you actually want to be on. Maybe it's rung 2 — and that's a perfect goal. Maybe it's rung 4 — and Lucy is built for you.
If you're rolling out AI for a team: stop optimizing for the demos at rung 4 and start optimizing for the muscle at rung 2. The math works in your favor. Get your whole team to rung 2 and you've already won most of the productivity gain. The handful who keep climbing to rungs 3 and 4 give you the upside.
If you're building the AI strategy for your company: the gap between "we have AI tools" and "we have AI capability" is exactly the gap we describe here. Closing it is not optional anymore. The companies that close it own the next decade. The companies that don't will keep wondering why their pilot didn't deliver.
