Absolutely. There will always be redundancy, but that doesn't necessarily mean pilot bums on seats.
I'll bet our distinguished flight engineers, navigators and radio operators never considered their own technical obsolescence a real possibility ~30, ~50, or ~70 years ago. Their activities still occur with full redundancy, but their roles have been integrated into aircraft systems and pilot duties.
The role of Cruise FO / SO is -very sadly- steadily drifting towards 'cruise relief' pilot only. Manufacturers, operators, and regulators are all going down this path. Surely the concept of 'remote relief' pilot isn't really that surprising as a next step?
