In my limited experience using copilot at work, i think it has been a game changer for non-technical computer users. Many of my coworkers and i use it as the first attempt at research especially now that it is connected to SharePoint within my company and provides references to the documents it is pulling from. Saves hours for things like compiling international regulations or standards documentation. Additionally, it has super charged (maybe too strong of a word) document search within our environment... Sharepoint search is the worst.
