"*Prometheus*" is meant to be a prequel to "*Alien*", happening 30 years before ([src][1]).

If that's the case, **how come one of the very earliest spaceships, Prometheus from 2089, has a spiffy new technology**, while **Nostromo has antique text based CRTs, mechanical IBM style keyboards, and all the associated technologies screaming "1980s called, and they want their IBM PC back!"** ?

The great visuals of this can be seen in this Youtube Video ([here][2] - ignore the russian voice-over - the guy is a movie critic who is complaining pretty much of the same discrepancy listed above).

<sub>Please note that I'm looking **ONLY for in-universe** answers (movies, scripts, explanations from creative team). I'm utterly un-interested in the obvious out of universe "well, for 1979 Alien film, 1980s technologies was the future, and 2012 movie is expected to look futuristic in 2012, duh".</sub>
