The SF / Marin Headlands area got more buildings in 150 years, but then most buildings were lost again, and they got more green areas and trees. Fun fact: The very old tree they remember actually wasn't there before XD
Maybe it was transplanted :P The 3180s model seem to have been modified from the 2250s model, not the Picard 2390s model.
So the in-universe redesigners preferred full retro... Given that this is San Francisco, the city probably gets leveled at least once every century, by those who don't love Starfleet, or then simply by earthquakes. Rebuilding sounds natural enough. And will happen all the more easily as the centuries pass. Timo Saloniemi
That abnormally girthy tree, the "Starfleet Academy, or at least it was", and everything in San Francisco are all just programmable matter. They reshaped them that way to humour the gullible away team. What’s more, United Earth reshape all their luxurious cities hourly just to waste energy and to annoy Titan colonists, who have eye bags that are clearly makeup. For Earthlings of this century, wealth hoarding and economic disparity have come back in vogue and in force, and on an interplanetary scale, no less.
This is the new replicant thing. I sense a short story coming: "Do Time-Travelling Tillys Hug Programmable Trees?"
It could be like the surviving tree at the 9/11 memorial - it was moved and recovered, then moved back after the cleanup and kept thriving. You can see the line between old and new growth.
What are the chances that bridge would *still* be there after 900 years? Then again, it was rebuilt once in DS9. And there was probably active dilithium tech in the city at the time of the burn, so I'm guessing the whole city has probably been rebuilt with their magic nanites in the recent past.
Probably been upgraded with tractor beam emitters to keep jumpers alive... I like to think of it as an enclosed park in the Trek future, with a variety of Earth and non-Terran gardens inside. It is a bridge, after all, and would celebrate the variety of different species of plants and animals across the quadrants.
Happily enough, Boothby's tree as seen in TNG was nowhere near the shoreline, where all the action always was: every time somebody destroyed the HQ or the Academy, they'd hit the scenic shores and the bridge, and the tree thus would survive. Eventually, though, the fact that the bombardments always vacated real estate at the shore, combined with the departure of Starfleet for good, would mean Boothby's tree would end up transplanted there so that her original safe location could be put to better use... And then the attacks ceased. Timo Saloniemi
