If I was Salesforce I would be scared of IRC. The best thing about the 80s and the 90s is the internet was pretty cool back then. Better yet, all those things from then are still running so if you get tired of Slack or Microsoft Teams, you can host chat for your entire 1000 person org on a raspberry pi now. It had bots and automation with API integration in the `00s. Oh yea search would work just as good. No search vs useless search...
