I know people who don't understand what a Server is and even they can use IRC. Not saying that it's as simple and convenient as Slack, but making it out to be this huge complex thing is being disingenuous.
My PM was able to set up Slack integration with Trello and Github in a few moments, and found that connection incredibly useful. She didn't have to KNOW that she wanted it, she just saw it on the list of possibilities. She didn't have to go looking for instructions, she just hit connect. She didn't have to ask me or one of the other consultants to stop billing project time to set up some tech for the office, she could do it herself.
In my firm at least, Slack is an incredible tool for our PMs and owner, and it also works well and covers all use cases for the consultants.
