My company recently really cut back on slack retention. At first I was frustrated, but we all quickly got over it and work carried on getting done at the same pace as before and nothing really got impacted like many of us imagined it might.
That bears little resemblance to the Signal concerns. The reason people are worried about losing their personal messages is not lost productivity.
It's also not even really the same situation. A more apt analogy would be, if switching work laptops sometimes meant you could no longer read any Slack history.
Once communication with my customers moved to teams. I've had a very hard time to find historical agreements and decisions.
I try very hard to create a robust system for ADR logging now. And not just for system architecture. But for all decisions and agreements in my projects and across changes.
Well I don't think most people choose who they work with. Even if you like your team a lot, you might have a discussion with someone from another team or division, and that's where it's useful to have a good chat history haha.
I'd hate this, slack is an extension of my memory and it being long lived and searchable can be a super power - you don't have to remember all the details of everything, just enough of the who, what, when to find the rest.
