I completely agree in terms of personal computing like storing photos, documents, notes, and so on. At most, they could be encrypted locally and stored remotely so that multiple devices can use the data.

There are still plenty of use cases for server-oriented data processing. Most "infrastructure" related things work well that way. Cases where data needs to be quickly read and written from a number of different locations and the information isn't really secret or personal. I am biased since I work on one of those systems. But there are so many internal systems at companies that really don't need end-to-end encryption either. Although maybe some day things will still move in that direction.
