Earlier the main reason was to allow for a human to revisit any important discussion of they missed making detailed notes. It also allowed anyone who misses the meeting to catchup. And for global teams, team members in other time zones can catchup and maybe rewatch the meeting of accent differences made following the live meeting difficult. The coworker tasked with writing the minutes (manually!) would find it super handy. We also did recordings for "requirements gathering", "design review", "prototype walkthrough", etc so we captured all feedback and nuances thoroughly so next iteration can address them all.
For all these benefits we sometimes opened a MS Teams bridge and turned on recording EVEN WHEN we were all meeting in person. I would switch on the webcam and turn it towards the whiteboard, and try to get the best clarity possible -- a service to anyone who might be watching afterwards.
I've worked with a team who did just that, they held the vast majority of their meetings in-person (1 or 2 short meetings a day) but needed other stakeholders to keep up with their work and decisions, so they had some AI listen, keep track and send summaries and minutes.
They liked it, but I'm not sure it was more efficient than having someone send half a page of meeting summary manually.
