Bay Area tech companies have made a huge impact on 21st-century living across the globe, but their day-to-day impact is hardly felt by people living around them. Tech giants like Google, Apple, and Facebook today have a much more subdued presence on the ground, and really aren't much to look at.
I grew up 15 minutes down the street from Apple's campus in Cupertino in the South Bay and drove past it hundreds of times. Had it not been for signs with the Apple logo, the buildings along the road would have been indistinguishable from any other run-of-the-mill commercial office spaces.
Since then, Apple has, of course, opened up a new, flashier campus. Visits to campuses like these are certainly eye-opening experiences, but by and large, people coming to the South Bay to "see Silicon Valley's tech world" might be a little bit disappointed.
Perhaps the most consequential way that these businesses have made their mark is by continuing to be some of the largest employers in the area, and over the years, they have driven housing prices to astronomical heights.
