I mostly agree, but I suspect not all CRUD businesses have been eaten. The ones that have been eaten have the following property:
-- You have to enter the information in yourself, or your equipment currently captures it for you
There are still CRUD opportunities where you find, capture and enter the information on behalf of the user. The phone captures a lot of data, so all that is already CRUDed up, but if you had novel data -- say from a wearable device -- you could still produce a new CRUD for that.
I think this is why hardware is hot again. It allows us to automatically capture new data that isn't already captured by the phone.
