I completely agree with you that being able to transmit and receive morse coed by ear is going to be an essential skill that should be developed now whilst there is time.
The problem, I see with manual CW is that it requires the operator to be at the station for some time and this may be risky, it is probably safer to have the message sent and received automatically. For this reason I think we will see automated CW or more likely auto digital modes
I also think that the most likely outcome of a disaster that results in loss of internet will be am RF based internet replacement and its anybody's guess what format will emerge as dominant, Simplicity and reliability and low power will guide the choice but I also think encryption (have posted separately about that) will become critical
