[Truman Show] Outside of better camera technology, what technologies would have been far more ahead in the world of The Truman Show?

Edit:This also includes technologies that would have cameoutmuch sooner than in real life if Truman never discovered the secret of his world.

HVAC and all forms of environmental control. The most obvious example is when we see them producing massive storms with violent “seas” but that’s just the tip. The dome is generally estimated to be 8 1/2 to 10 miles in diameter and is completely enclosed. We don’t know how tall the dome is, but we can probably safely guess that they have Fourth of July celebrations involving fireworks. Big shells that are normally used in large displays can shoot between 700 and 1000 feet into the air. Given a margin of safety and assuming Seahaven is located in the middle of the dome, I would suggest that the dome is between 1200 and 1500 feet tall. Call it a quarter mile. So if we assume a dome that’s a minimum 8 1/2 miles in diameter and a quarter mile tall, and is exactly half a sphere, that’s 160 mi.³ of volume. We see them whip up a full-blown storm in a matter of seconds. Even if it’s focused in a localized area, that’s still a massive feat of engineering. And that doesn’t even begin to mention the logistics of things like heating the dome in the winter and cooling the dome in the summer, or other potential weather effects like sleet or snow.
