The digital divide in the Alien franchise

I wrote this first as a reply to a YouTube video that comments about why the tech in "Alien" is so outdated compare to "Prometheus", which canonically took place many years previous to the events in "Alien".

I think, that there's a digital and class divide of sorts: the miners get CRTs on the ships they run, which is just enough to get the job done, and the scientists get all the fancy stuff. — But not always, if the company knows, that any such mission with the xenomorphs is doomed from the outset. And anyway, the most advanced thing onboard Nostromo was Ash. The most advanced thing in Aliens was the atmospheric processor.

I can guess, that at some point, Weyand-Yutani might have thought it cheaper to recycle old technology than to mine and make new stuff, because they came to be short on resources back on Earth and any colonies. The Nostromo was sent out to bring back the very necessary readymade ore to manufacture new things, but its mission failed.

A good explanation is, indeed, that for certain objectives, obsolete[-looking] tech is used.
