put the work off until the weekend when there's no expectations of responses and spend the actual weekdays talking about work.

which I just don't get.

That is not economically productive.

Companies are leaving money on the table, but it's just where we are.

We really can't quit this behavior.

It wasn't big.

It wasn't out yet.

I talk in Deep Work about these very early instant messenger tools that no longer exist, like HipChat.

It was just emerging among the programmer class.

I was basically saying, there be dragons, like, let's be careful about that.

But I wrote an article about Slack

years later when Slack was bought.

So I think Salesforce bought Slack.

I wrote an article about it for the New Yorker.

And I think the title of that article gets to the core of the issue you're talking about.

The title was Slack is the right tool for the wrong way to work.

And I think what happened, here's my whole theory on Slack, is that when email arrived,

it moved us to this new style of collaboration that I call the hyperactive hive mind, where we'll just figure things out on the go with ad hoc back and forth, unscheduled messaging, just sort of like shooting messages back and forth.

We'll figure things out like we're all just kind of connected all the time.

That's a terrible way to work for all the reasons I talked about.
