Seattle is basically a great place to work for a satellite office of one of the tech behemoths, but the actual hacker / enthusiast scene seems to have pretty much dried out. Seattle's Linux user's group died in 2020 and never came back, as an example.
Madison had much better makerspaces and more of them, despite being a much smaller city. Madison was also small enough that you ended up connected to a lot of really smart people coming out of the university's CS / biomedical departments which seemed to sustain a pretty vibrant med-tech startup ecosystem.
Edit to add: If anyone in Seattle does have meetup groups they enjoy, I'd love to hear about it! Hardware, electrical or software; I'd be up for any of them.
