Re: Spinning Tendrils
Whether the Jellyfish represented advanced technology or not, we don't really know. It was the fastest ship Spock could get his hands on, but this may simply mean he got the decrepit old scooter from the Vulcan Science Academy when the government refused to give him a proper warship or courier vessel. There are no scenes where the Jellyfish would demonstrate high speeds, and indeed Nero appears to think it possible to chase after this craft in his slow-as-molasses mining rig after Spock destroys his drill.
The ship's computer does report a commissioning date of 2387, about nine years after Voyager's return to Earth.
