This starts off strong, but then ...
>I'm 39. I've been in technology in a professional capacity for 22 years, longer now than perhaps a few folks on HN have been alive. I wrote my first computer programs over 30 years ago, started online with local BBSs and then eWorld and then the internet.
If I were typing this in slack, this is where the first :facepalm: emoji would appear.
This is the mentality that caused the now-semi-famous HN post in the early days of dropbox, arguing that it was useless because with a combination of [ simple CLI tools that nontechnical people have never even heard of ], you could create the "same" functionality.
Say it with me: Being so simple that utterly nontechnical people can use (edit: not just 'use', but 'deploy and administer') IS important functionality. That's what made Dropbox, and it's what's made Slack. You don't have to be an IT pro to deploy it successfully. You don't have to be a programmer. You just click half a dozen buttons, all of which are helpfully color coded so that your unwillingness to read any text on the screen won't be an obstacle.
Yes, there are things you lose when you "build infrastructure out of walled gardens" -- but the reason some people prefer cathedrals vs bazaars is that they often have much lower barriers to entry, and for many people that is a worthwhile tradeoff.
