Neither of those is going to be obsolete in 5 years. Might get rebadged and a bunch of extensions, but there's such a huge install base that rapid change is unlikely. Neither Firewire nor Thunderbolt unseated USB.

USB4 is the ~third USB protocol stack though (USB1/2 being basically the same iirc, USB3 being a completely separate protocol that neither logically nor physically interacts with USB1/2 at all), heavily based on Thunderbolt to the point of backwards compatibility.
