Calculus of IT - Season 3 Episode 6 - Slack as an OS

So Mike and I set out to answer a simple question: What actually constitutes an operating system in 2026? Turns out, it depends on whether you're talking about computers or how people actually work. For a computer OS, you need hardware management and file I/O. For a business OS, you need the thing that, when it goes down, everyone goes home. By that definition, Slack is absolutely an operating system. Nobody in your company can tell you what OS version they're running, but everyone knows their Slack workspace name. The desktop is dead. Your actual "desktop" is just a browser, Slack, and some cloud storage shortcuts. For most users, you could swap Windows for Mac or Linux and they wouldn't even notice. The uncomfortable truth: if Slack is where you spend your entire workday, Slack IS your OS. The thing underneath it is just infrastructure. Mike thinks the computer OS should become invisible while the business OS (Slack, identity platforms, automation) becomes the focus. Nate thinks we're heading toward a world where everything runs in browsers and the OS is just a launcher, probably Linux-based, definitely not what we have now. We also proved you could recreate email using Box notes and @ mentions (terrible idea, technically possible), went full nostalgia on OS/2 and BeOS and Adium with the duck, and discovered Mike hasn't touched his Vision Pro in months but is still paying $29/month for AppleCare. Oh, and Nate will assume you hate him if you don't respond to Slack messages within 7 minutes. The autonomy problem looms: if Slack becomes your OS, you're locked in. Convenience breeds dependency. Next week we're diving into what has become of chat - the full timeline from IRC to Slack, and why instant messaging makes us hate each other. Also, Flock is watching you. Is that really ok?
