Yeah, right now you have to take advantage of the offline apps that there are. Outside of that you just have to wait a little longer until offline apps are further developed.
Many places I have seen are requiring something online for work. Such as Sharepoint, Google Docs, Office Online and such. Also since you can connect via Mobile Data..you can always have a connection of some kind...**** my gas station by the house advertises Free WiFi...Your internet goes out when a project is due. Can you do anything with your Chromebook? Or are you forced to search for a 24 hour restaurant with free internet? Can you save a copy of the project that you could use on a windows based laptop?
