Just to start with I hate the idea of hard vs. soft sci fi, I’m just curious and want to talk about it.
Films such as 2001 and Moon get held up as hard sci fi, but neither really fits. In 2001 you have the monoliths of mysterious origin that can do things like change the intelligence of animals/change their genes and transport people and many other impossible things, in Moon it is possible to read and write a human mind and create human clones already aged.
For 2001 I concede apart from the monoliths its hard sci fi, all the tech is physically possible and an extension of current science. If the argument is that alien tech so advanced it is identical to magic is allowed well hell then hard sci fi is meaningless.
But for Moon there is nothing to suggest we will ever be able to record and write human minds and memories in current science, not to mention being able to clone pre aged human bodies.
I’m trying to think of sci fi films that feature only physically possible or advanced forms of tech that already exist and coming up very short.
Outland - Sean Connery, space colony setting but nothing thats impossible by current standards(I forget if they ever mention anything about FTL on their ships).
There area LOT of near misses that feature one big impossibility, or alien tech or aliens.
On TV I have seen many call Babylon 5 hard sci fi which is a joke, and Star Trek is probably the softest sci fi unless you include sitcoms and obscure stuff. Not only do psychic powers exist but humans and aliens freely procreate together:smack:
