Why 'Star Trek' made San Francisco the center of the universe

It features prominently in the fourth movie, The Voyage Home (which was funny AF when released, but unfortunately a good amount of the jokes fall flat now). It's where Starfleet HQ is located, and so is a recurring setting in pretty much all the various spin-offs & movies.

The fictional future StarFleet is headquartered here, and Star Trek IV movie was set here in SF and the Bay Area.
