They Built Too Much State Here

Inspired by Julian Shapiro episode

Julian Shapiro explains why users stick to products—they've built non-transferrable state. Your kid who melts down over routine changes? Same thing. They've built state.

Julian's retention secret: users build state they can't transfer. eBay sellers with 10,000 ratings won't leave—too valuable. YouTubers with a million subs can't move them elsewhere. The more state you build, the harder it is to leave.

Your three-year-old has state. They know which preschool bathroom stall doesn't have scary auto-flush. They've identified the "good cup." They've mapped when dad's more likely to approve snacks. That's hundreds of hours of accumulated local knowledge.

Then you change preschools. Move houses. New car. Suddenly their entire database is worthless. Bathroom stalls are different. All cups are wrong. Dad's snack patterns unmapped.

That's why transitions wreck them. Not drama. They lost everything they built. Like telling a YouTuber their million subs vanished.

Give them time to build new state. It's not resistance. It's reconstruction.
