Note: When Kevyn Andreyasn invented the Teraport nobody, least of all Kevyn himself, knew that what he was inventing had been invented and widely deployed before. Its modern rebirth and escape from Gatekeeper suppression started countless small wars, and finished one very large one.
Galactic society has, at present, only had Teraport technology for a few years. Mounting evidence suggests that at least one prior galactic society had access to this technology millions of years ago, and used it for hundreds of thousands of years. Indications that they abandoned it and suppressed it before dying out completely are the sort of disturbing line-items ignored by right-thinking folks who like to sleep well at night.
