Well for me personally the incentive is currently that I ensure that I have a backup of all my own notes and replies. Otherwise they might disappear.

It is like with every technology - you need personally time to master it and when we talk on a society level it is the same, but much slower. Even nowadays most of the people did not understand the dependencies which they have on large corporations - until their data is gone.

Incentive comes when their is a need to, but obviously the tools need to be available at this time.
