Commuting and residential patterns changed too. A lot of Googlers purchased houses in the Tri-valley during COVID instead of living in apartments in Mountain View or Sunnyvale or SF. Now they have a Dumbarton or 237 commute instead of something Caltrain-accessible. Tech companies also started laying off in 2022, and stopped hiring in the Bay Area; I'd bet that total employment along the Caltrain corridor is significantly lower than in 2019.

The Bay Area also needs way better last-mile transportation. I looked into taking Caltrain to work; it'd take 22 minutes to Caltrain the ~15 miles to the nearest Caltrain station, and then another 22 minutes to shuttle the 2.5 miles to work.
