Today only the aggregators have the accumulated user context to make truly assistive features.

This is because the easiest way today to have access to the context is for the service to be able to see all of the data.

That means the user must have very high levels of trust in the creator, accelerating the aggregation effect.

By flipping the privacy paradigm on its head, indie creators will have the same amount of context to build with.

The only trick is: they can't see the context.

Instead, the creators will describe the operations to do on the context to produce a useful result.

Think of allowing creators to give a pre-programmed algorithm for a remote control robot to follow that, once in motion, they can't tweak.
