- B5’s ideas of how long technology will remain in use are… interesting. In the B5 universe, production of gas-powered vehicles will apparently come to an end within twenty-five years, but ‘VCR’ will remain a term in common use for several centuries to come.

These are no contradiction. Technologies and the words for them are very different things. The latter tend to stick round much longer and get transferred from one thing to the other. Note that VCRs in the B5 universe are no nothing like the kind of thing I'm currently using to rewatch my old B5 tapes.
Or, to take an example from the real world, a spaceship has very little to do with watercraft!
