This is a legal concern in some places (like Germany). In many places recording without consent is illegal. But on the other hand, you should at this point assume that this may be happening regardless as you simply can't exclude the possibility. The best thing is to just be open about it if you want to record and assume you are being recorded otherwise.

Some of the tricks that big companies use to avoid being recorded, like forcing everyone to use their MS Teams or whatever else they use of course don't work. And if you go into a situation where you might have lawyers demanding and getting access to documents, you might want to think twice about having any transcripts of certain meetings. Those could be used against you.

But on the other hand, it's very annoying to have meetings without transcripts these days. They really help staying organized if you do a lot of calls. I get involved in a lot of sales and other business calls and a lot of the prep work for those involves figuring out the basics of who am I talking to, what's our history with this contact and what did we discuss before, etc. Having full context with transcripts enables concise briefings, quick follow ups, etc.

The reality here is of course that many people are going to end up using AI to record, translate, summarize, and analyzing more or less 24x7. This is becoming so cheap and easy that there's no technical reason to go offline by default. You might still want to for very confidential meetings or personal reasons. But there are going to be lots of people around you that will make different choices.

Reflecting on my own situation, I could definitely benefit from a diligent always on note taking personal assistant that translate any off the cuff remarks, encounters, casual conversations, etc. into actionable things. A lot of that is lost in the moment with me. I'm too chaotic to do this myself. Also, I can't multi task all that well. Writing and listening at the same time is hard for me. Especially when I also am trying to participate in a meeting (which adds thinking and talking to the task load).
