We're already moving towards completely distributing the team, all remote. 2016/17 seems to become the year when remote-default teams become not just possible, but easier than co-located teams. The tools are almost there.
Unfortunately, not everyone uses the command line. Not everyone is comfortable with it. Additionally, even if you are (like me and my team), it's not collaborative. If I run a query in my team's room, they can all see the results and we can easily discuss it. Did I mention on the go with Slack for my phone? Can't do that with CLI.
Slack also supports link embedding, images and more. All things not supported by CLI.
Also everyone can see what you type and the response. Cuts down on the "did you run it with the dash k flag?" And "what was the response" back and forth.
To me that's the killer feature. It is searchable and so you can look back in time and see others that ran similar commands and what the response was.
