It does not. You can fully expect the universe to go down before that happens.
The only reasonable worry is about SHA-1 being broken some time in future, i.e. being able to construct a malign version of some source code _which has the same hash_. There were plenty of discussions about that; Please search the mailing list. (The consent was that those do not matter, because an existing object will _never_ be overwritten by a fetch, so you would not get that invalid object anyway.)
