This article and the one it is responding to are explicitly talking about non-business meeting contexts. They are talking about personal conversations, medical appointments and much more casual business contexts like informal interviews. Places where there would never have been a secretary present.
To a physio therapist (the article example) that is a business meeting. That's what's strange here. That person isn't there because their you're friend: they're getting paid to be there, which makes it a business meeting, which makes a secretary, human or AI, appropriate.
Does /anyone/ take notes in a personal context? I don't take notes when I catch up with friends, but neither does anyone else. It's a complete non-issue.
medical appointments is a perfect use case for ai note takers. Imagine you have an elderly parent who lives hundreds of miles away. You can't always be present for their medical appointments, yet, the outcomes of those appointments are critical, and sometimes information is shared in a way that the elderly parent cannot be a trustworthy source for that info. What do you do?
