I agree! The possibilities a mind-boggling! As an aside,“This Island Earth” is one of my favorite movies. Saw it at The Willow Theater in 1955, when I was 9!
This movie needs a serious remake, though I don’t criticize anything about the original. Another I like is “Forbidden Planet” which was groundbreaking as it influenced a host of directors and sci fi writers. One can see its influence on the Star Trek series, for example.
