I think authentication will be huge.
Lots of commercial alternatives are starting to bet on the future (eg https://swear.com/), where something gets fingerprinted and the fingerprint gets signed and put on an authentication block chain (something block chains are actually useful for).
I imagine a future where this gets built into browsers (ie “this picture was verified by NY times, and it went through this editing chain, starting from a canon camera which recorded on this date”) and you can switch over to have unauthenticated assets highlighted.

Constructed vs evolved.
