CGI is just another tool, capable of being used for good or evil.
I suppose that you opposed talkies when they first came out, eh?
Oh, wait....that was a little before your time.
Ridley Scott filming model shots of the Nostromo and its attached ore refinery. He made slow passes filming at 2½ frames per second to give the models the appearance of motion.
[16]
The spaceships and planets for the film were shot using models and miniatures. These included models of the Nostromo, its attached mineral refinery, the escape shuttle Narcissus, the alien planetoid, and the exterior and interior of the derelict spacecraft. Visual Effects Supervisor Brian Johnson, supervising modelmaker
Martin Bower, and their team worked at Bray Studios, roughly 25 miles (40 km) from Shepperton Studios where principal filming was taking place.
[53][54] The designs of the Nostromo and its attachments were based on combinations of Ridley Scott's storyboards and Ron Cobb's conceptual drawings.
[53] The basic outlines of the models were made of wood and plastic, and most of the fine details were added from
model kits of battleships, tanks, and World War II bombers. Three models of the Nostromo were made: a 12-inch (30 cm) version for medium and long shots, a 4-foot (1.2 m) version for rear shots, and a 12-foot (3.7 m), 7-short-ton (6.4 t) rig for the undocking and planetoid surface sequences.
[16][54] Scott insisted on numerous changes to the models even as filming was taking place, leading to conflicts with the modeling and filming teams... He ordered more and more pieces added to the model until the final large version with the refinery required a metal framework so that it could be lifted by a
forklift. He also took a hammer and chisel to sections of the refinery, knocking off many of its spires which Bower had spent weeks creating. Scott also had disagreements with miniature effects cinematographer
Dennis Ayling over how to light the models.
[53]
A separate model, approximately 40 feet (12 m) long, was created for the Nostromo's underside from which the Narcissus would detach and from which Kane's body would be launched during the funeral scene. Bower carved Kane's burial
shroud out of wood and it was launched through the hatch using a small
catapult and filmed at high speed, then slowed down in editing.
[53][55] Only one shot was filmed using
blue screen compositing: that of the shuttle racing past the Nostromo. The other shots were simply filmed against black backdrops, with stars added via
double exposure.
[54] Though
motion control photography technology was available at the time, the film's budget would not allow for it. The team therefore used a camera with wide-angle lenses mounted on a drive mechanism to make slow passes over and around the models filming at 2½ frames per second,
[16] giving them the appearance of motion. Scott added smoke and wind effects to enhance the illusion.
[53]...
A separate model was created for the exterior of the derelict alien spacecraft.
Matte paintings were used to fill in areas of the ship's interior as well as exterior shots of the planetoid's surface.
[53] The surface as seen from space during the landing sequence was created by painting a
globe white, then mixing chemicals and dyes onto
transparencies and projecting them onto it.
[16][54] The planetoid was not named in the film, but some drafts of the script gave it the name
Acheron[36] after the river which in
Greek mythology is described as the "stream of woe", a branch of the river
Styx, and which forms the border of
Hell in
Dante's
Inferno. The 1986 sequel
Aliens named the planetoid as "LV-426",
[48] and both names have been used for it in subsequent
expanded universe media such as comic books and video games. In Alien the planetoid is said to be located somewhere in the
Zeta2 Reticuli system.

That's just a tiny portion of the awesomeness in effects, and only deals with just the shooting of space and ships, not all the fun fleshy stuff.
Brothers Robert and Dennis Skotak were hired to supervise the visual effects, having previously worked with Cameron on several
Roger Corman movies. Two stages were used to construct the colony on LV-426, using miniature models that were on average six feet tall and three feet wide.
[19] Filming the miniatures was difficult because of the weather; the wind would blow over the props, although it proved helpful to give the effect of weather on the planet. Cameron used these miniatures and several effects to make scenes look larger than they really were, including rear projection, mirrors, beam splitters, camera splits and foreground miniatures.
[19]
The Alien suits were made more flexible and durable than the ones used in Alien, to expand on the creatures' movements and allow them to crawl and jump. Dancers, gymnasts and stunt men were hired to portray the Aliens. The translucent dome that gave the creature's head its sleek shape in Alien was eliminated because of its fragility at Cameron's insistence, exposing the ridged, spined cranium beneath.
[20] Cameron also felt that Giger's cranium design was more visually interesting without the dome.

Scenes involving the
Alien queen were the most difficult to film, according to production staff. A life-sized
mock-up was created by
Stan Winston's company in the United States to see how it would operate. Once the testing was complete, the crew working on the queen flew to England and began work creating the final version. Standing at fourteen feet, it was operated using a mixture of puppeteers, control rods, hydraulics, cables, and a crane above to support it. Two puppeteers were inside the suit operating its arms, and sixteen were required to move it. All sequences involving the full size queen were filmed in-camera with no post-production manipulation.
[19] Additionally, a miniature alien queen was used for certain shots.

Pretty cool, but that's it, in comparison to how much work had to be done a decade before?
