Less than 34% of projects are completed on time and one budget, Dresser claimed, saying that users having to switch between tasks in applications was a significant drain on time and productivity. “We have millions of people working in Slack; why leave Slack?”
Yes, context switching is expensive. I don't see how never leaving Slack changes that, there is enough going on there to make it hard to stay on task. Plenty of windows, DMs, channels, integrations pinging you, meetings about to happen.
I can only imagine they are starting to dream of SlackOS where everything is AI powered and you never leave Slack but you are still wasting the same amount of time, just in their product.
