I think the valuable part would be the soft skills of thinking and working while having 12 things blinking and beeping for attention a keystroke away. This is how I have to work -- need to be available on Slack, watch out for urgent email, keep an eye on some dashboard for a service that is acting strange but not in a way that anyone is calling an incident yet, watch for Outlook reminders of meetings coming up). You're right that pencil and notebook is probably a better way to /retain information/ but that might need to be a separate kind of lesson from one about /existing in a 21st century information environment/.
