The technology, [often so prescient it borders on creepy,] has made
Chinese counterparts very profitable too.
The commas mark the bracketed adjective phrase as a supplement, a loosely attached expression set off by punctuation (and intonation) presenting supplementary, non-integrated content.
Supplements are not modifiers; rather, they refer to an 'anchor' -- in this case the anchor is the noun phrase "the technology". By virtue of not being integrated into the syntactic structure, supplements are necessarily semantically non-restrictive.
Supplements with the form of an adjective phrase, a noun phrase or a preposition phrase most often function as predicative adjuncts:
Bob, [angry because Joe has married his ex-wife Sally], forces Joe's car off the road. (adjective phrase)
[A proud teetotaller], John stuck to water while the others drank
champagne. (noun phrase)
[In a bad temper], as usual, John walked on ahead of the main party.
They are called predicative adjuncts because they are related to a predicand. For example, the adjective phrase "angry because Joe has married his ex-wife Sally" refers to "John". It can be compared to the predicative complement in Bob was [angry because Joe has married his ex-wife Sally].
