When you look at top pay by region I'm really surpised to see such a small difference between SF and Pitsburgh. Considering the insance COL here in the bay area, I would expect bay area to pay at least 3 times more than pistburgh. as far I can tell SF and Palo alto are vastly vastly underpaid and the likes of Pitsburgh are extremely overpaid.
I think the numbers seen here for Pittsburgh miss a big part of the picture. There are only a handful of big tech companies with offices there and they employ a comparatively small number of engineers. Most engineers in Pittsburgh are not working at those companies and do get paid 4x less. These are pretty much dedicated AI offices that recruit from CMU and are companies that don't adjust pay much between locations
