> People have calls instead of figuring it out.

I find the opposite, I can often help my coworkers debug something pretty quickly via a quick Slack call and screen sharing session, whereas other times I have seen similar problems resulting in hours of struggle as someone tries to 'figure it out' on their own without being able to tap the expertise of someone who's familiar with the problem or system at hand.

That said, there are definitely downsides to the abundant distractions through Slack as well.
