My girlfriend and I (both in tech) have also left San Francisco as of last month, but for slightly different (but related) reasons. The 75,000 mentioned people who have moved to the bay area for tech have caused rent to rise by such a large amount, that even though we can afford to pay, it feels like a huge waste of our money. We could be spending it doing other things or just saving for our future.

Instead we'll continue to work in tech doing consulting work, but we're going try our hand at being completely nomadic while doing it (starting with Central and South America, though we'll be picking a place and staying there for a few weeks to a month at minimum). We've sold pretty much everything we own and have whittled down our belongings to a large backpack and daypack each. It feels pretty amazing to be this lightweight and mobile, and our current budget has spending about 3x less than we were while living in SF (and still living very well).
