Why the Skeptics Called It Right

When AI vendors themselves publish warnings about using AI for factory automation, it's worth listening. This episode launches a new series on industrial controls by examining why both skeptics and Silicon Valley agree: AI hasn't solved manufacturing yet. From Unitronics' cautionary tale to the fundamental challenges of deterministic, safety-critical code, we explore the gap between AI hype and factory floor reality. 0:00 - Opening: The case for human oversight in factory code 2:30 - The irony: AI vendors warning about their own products 5:45 - Why factory automation is different (determinism, safety, certification) 9:15 - The research question: Why hasn't AI disrupted manufacturing? 13:00 - Introducing a new series on industrial controls --- Sources & further reading: • All URLs fetched on 2026-09-22 unless marked internal. • [vendor, primary for its own definitions] Rockwell Automation, "Programmable Controllers" • product page: https://www.rockwellautomation.com/en-us/products/hardware/programmable-controllers.html • — the PLC definition, the FAQ, and "this cycle repeats in milliseconds."
