For years the advice ran one way: pick a single skill, build depth, and climb. Broad interests looked like a failure to focus. AI changed the setup, so a designer now writes and a writer produces visuals. A marketer automates workflows that a small team once handled, and a founder builds products that a whole department once owned. Each of those jobs used to need several people and a budget to match, but one person can get the same software for a monthly fee. What stays scarce is knowing how the pieces fit together.
The change has a name, the squiggly career, in which people move across roles, industries and disciplines with no single track to climb. Some of the most valued people in this market hold depth in several fields.
A simple model describes how people get there. The I-shaped worker has one deep skill and relies on others for the rest. The T-shaped worker keeps that one deep skill and adds enough grasp of nearby fields to work with the people in them. The pi-shaped worker, named for the two legs of the Greek letter pi, has two deep skills plus a working knowledge of everything else. Each step widens the range while the depth stays intact. AI pushes more people up these steps, because it gives one person the means to build a second deep skill and put both to use. That second skill makes the difference, since two strong areas joined by broad range produce work that a single specialty rarely covers.
Specialists are not disappearing. Deep expertise still wins on hard problems, and a single strong field still carries weight in the market. But the tools keep getting easier to use, while combining skills keeps getting harder to copy, which is why breadth has become what the market rewards.
The reward shows up inside the work, where one person carries an idea from design through to data, with no file waiting on the next desk. Someone fluent in two fields reads a problem in both at once. A marketing problem and a product problem reach one desk and meet a single answer, so the friction between two teams turns into one person’s working knowledge.
