I can understand, especially in a medical context, being bothered by AI notetaking specifically because it implies your private information being handed off to a third-party where you cannot control it, rather than that an AI tool is processing it. That said, it is common practice in business to take notes or record calls. I take notes either by hand or type-written in nearly every meeting that I'm in. I often record my meetings. When it's entirely within my company, we have an internal (e.g. not third-party) AI transcription tool that I enable. When meeting with external entities, I either write notes, record audio, or have a designated person with me to write notes.

Taking minutes/notes in a meeting and then being accountable to follow-up on any action items out of that meeting is just standard business process across industries and across the globe. That's not what the author is referring to with their therapist, that's a very different context, but in the context most people on HN find themselves in, having someone take notes is not only not a big deal, it /should/ happen.
