While Slaughterhouse-Five doesn't emphasize science and technology as much as other Vonnegut novels like Player Piano and Cat's Cradle, the limitations of technology still play a crucial role. The destruction witnessed during World War II was only possible due to technological "advancements," such as the long-range bombers that decimated Dresden and the poison gas utilized in concentration camps. Additionally, the advanced technology of the Tralfamadorians not only fails to prevent the end of the Universe but actually causes it: "We [Tralfamadorians] blow it up, experimenting with new fuels for our flying saucers."
