If your use case fits within one silo, the silo probably does a pretty OK job at that use case.

If the app or service you're using has all of the data it needs to do a good job at a use case, then it's probably done a pretty good job at that use case, and beat out other services for the same use case that didn't do as good of a job.

But some use cases cut across silos, they require data from different contexts to be used together.

The use cases that will be most powerful will be the ones that cut across today's silos.

The cross-cutting use case will have a lower bar to clear to be viable, because there isn't a viable competitor today.
