The culture is similar here though, especially on the eastside where I live. Lots of teslas and other toys in the parking lots. Lots of overpriced high and midrise condos. My wife and I talk about it looking more and more california every day up here.
I'm east side Seattle as well, and it's kind of stupid up here. It's not as bad as SoCal, but it's headed that way, in a hurry. Friends who have purchased houses have had to fight the bidding wars with "Waive the inspection, cash up front, 15% over asking!" buyers (usually from out of the country). New construction is $700k+ for your standard 3k sq ft McMansion on a Lot(TM) (minimum setbacks allowed by law), with the "nice" ones going for $900k+. A friend of mine commented, "I'm a computer scientist and I can tell they're just thrown together as quickly as possible..." - usually with heavily restrictive and expensive HOAs as well.
Seeing my first Tesla Model S was cool. Seeing the 100th or 1000th one... meh. At least they don't pull out in front of me when I'm ebiking. Also, Leafs are everywhere. The cars, not the other kind that's everywhere.
The cost of living is high and getting higher, and there's no real sign of a break in that trend any time soon. We're in the middle of exit plans - the salary is nice, the job is amazing, but the area is just not our thing. So, off to the middle of nowhere we go. :) (actually, not, but you can see it from there, and we have family in the area, plus we just had a kid 6 months ago, so... lots of reasons to move)
It really depends on what you want. If you can live cheap and make a $fuckton of money (rent a room instead of a house/apartment, walk/bus to work, save 70-80-90% of your salary like I suspect some of my coworkers are able to do - some of them still live with their parents), you can set yourself up for life in a few years. Yes, there's a lot of flashy wealth, but there's also an awful lot of stealth wealth. Nobody talks about it, but you can do the math and come to some conclusions, and it occasionally comes up when someone laughs about the concept of a mortgage. "Mortgage? Why would you do that when you finally buy a house?" :)
Ten years of tech wages and living cheap, you're comfortably past a million, and haven't exploded your lifestyle such that you need it. It's not compatible with relationships/marriage/kids/etc, for the most part, but it's certainly an option to consider.
