I get what you’re saying, but internal company communications (especially for publicly traded companies) still should be accessible to valid legal inquiries, otherwise there is absolutely no hope for any kind of accountability. Having IMs between end-users be off the record by default seems totally reasonable and good to me, but internal communications should not be deletable at all, let alone manually by executives. The US Government has record retention schedules, through which non-records (water-cooler talk or the digital equivalent) are kept private and real records are identified and preserved. This is the kind of thing that Congress needs to regulate for private companies. Google blatantly and actively deleted conversations they knew would be relevant to the case, that’s unacceptable.
Ugh someone recently sent me LLM-generated meeting notes for a meeting that only a couple colleagues were able to attend. They sucked, a lot. Got a number of things completely wrong, duplicated the same random note a bunch of times in bullet lists, and just didn’t seem to reflect what was actually talked about. Luckily a coworker took their own real notes, and comparing them made it clear that LLMs are definitely causing more harm than good. It’s not exactly the same thing, but no, we’re not there yet.
