I lived in that area in the early 1980s. The changes are astounding. This was before it became Silicone Valley. It was just a mediocre suburb mid-way between San Francisco and San Jose. There were a ton of cheap apartments just off the freeway that catered to off-base housing for Moffett Field when it was still a Navy air base. There were quite a few Japanese Americans who'd settled there after returning from the Internment camps after World War II; there were even a few berry farms still around in the early 1980s. A lot of the houses were small post-war stock, most of which has been torn down and replaced by McMansions now. Just SE of Moffett Field, where there are a lot of business parks, was all tidal swamps and estuaries in the South Bay. Those business parks are all built on landfill. BART had not yet extended down past Palo Alto.

When I visited there a few years ago, shortly before the pandemic, it was almost unrecognizable to me, compared to the 1980s. About the only visible frame of reference that I could recognize from 40 years ago was Highway 101 and the old blimp hanger.
