Overall though, I think the amount of satisfaction (or frustration) you get out of any work place communication app is largely dependent on your management and work environment. If they’re that concerned about you needing to stay logged into an app all day (be it Slack, Water Cooler, etc.) and not about your work output, then it might be time to reconsider your options.
It’s not like making Nukes kind of tech where the harm is very obvious and people restrain themselves from making it in general.
It’s like farming/industrial revolution/social media kind of irreversible change where people actually welcome it and realize the evils a few (or a few hundred) years later.
That said, power to you if it catches on because If this succeeds and you make a ton of money, you will not be needing to be part of any room while you will be enjoying the money you earned by making the few productive office workers’ day less productive and more annoying while making countless believe-anything office workers‘ “feel” they are more productive.
