For as long as I’ve been in startups, execution speed has been the thing teams optimized for. The assumption was always that if you could just build faster, you’d win. That’s your moat. AI has mostly delivered on that promise—teams can now ship in weeks—see Claude Cowork—what used to take months. And the result is that a lot of teams are building the wrong things faster than ever.
Gale Robins, writing for UX Collective, opens with a scene I’ve lived through from both sides of the table:
I watched a talented software team present three major features they’d shipped on time, hitting all velocity metrics. When I asked, “What problem do these features solve?” silence followed. They could describe what they’d built and how they’d built it. But they couldn’t articulate why any of it mattered to customers.
Robins argues that judgment has replaced execution as the real constraint on product teams. And AI is making this worse, not better:
What once took six months of misguided effort now takes six weeks, or with AI, six days.
Six days to build the wrong thing. The build cycle compressed but the thinking didn’t. Teams are still skipping the same discovery steps, still assuming they know what users want. They’re just doing it at a pace that makes the waste harder to catch.
Robins again:
AI doesn’t make bad judgment cheaper or less damaging — it just accelerates how quickly those judgment errors compound.
She illustrates this with a cascade example: a SaaS company interviews only enterprise clients despite SMBs making up 70% of revenue. That one bad call—who to talk to—ripples through problem framing, solution design, feature prioritization, and evidence interpretation, costing $315K over ten months. With AI-accelerated development, the same cascade plays out in five months at the same cost. You just fail twice as fast.
The article goes on to map 19 specific judgment points across the product discovery process. The framework itself is worth a read, but the underlying argument is the part I keep coming back to: as execution gets cheaper, the quality of your decisions is the only thing that scales.
