There isn't a company in the world (except maybe Microsoft, with Outlook, and Azure to build on) who are in a position to even think about stepping in to replace Google's biggest services, and the businesses that are built on, and integrate with, them. Even with a year's notice, let alone overnight.
I think you're drastically underestimating the scale (and number - you missed Google Maps, which is bordering on an essential service) of these systems, the degree to which people rely on them - both businesses and individuals - and the difficulty of replacing them.
If Google failed overnight it would be a macro-economically significant event.
