This already happens all the time when starting remote offices, but not when moving the HQ. Employees who aren't attached to SF life or open to change of environment are willing to make the move. The pay vs cost of living usually works in their favor too. Smaller startups usually hire remote or start second HQs to tap into and train cheaper engineers outside SF. However, the post you're replying to was talking about larger startups moving INTO the bay area not out.
