Back in 2019, I was amazed to learn just how many buildings in Seattle's downtown were Amazon offices. IIRC, it was dozens of buildings, some entirely owned by Amazon, some WeWork leases, etc. Downtown isn't very big, so that's a huge presence. It was also fun to check out the company-city that is Redmond, not far away. Seattle's a great city, and it's got great tech presence. I'm optimistic for its recovery.
Despite the graph shown in the article, I have to wonder if this is really a new problem.
