I lost a client to AI and it taught me something I didn't expect

A little while ago, I lost a client I'd worked with for over a year. They were happy with my work, paid on time, and had no problems. Then, one month, they told me they were going to try handling it in-house with an AI tool instead. It stung more than I expected, partly because there was nothing I could point to as the reason. I hadn't done anything wrong. They just found a way to get something close enough for a fraction of what I charged.The work they replaced was the simple, repeatable stuff I'd been doing on autopilot. It was easy money for me, so I never questioned it. AI was always going to take that piece first. What I learned is that the safe work was the boring work, and the boring work was the most replaceable. The clients who stayed are the ones where I do the messy, judgment-heavy parts that a tool can't reason through on its own.Have you lost a client to AI? What was the work they replaced, and did it change how you position yourself now?
