I'd argue that the technology for digging up city streets hasn't needed to improve (though the politics around zoning/regulation/rights probably could); whereas, the technology for fixed wireless has--by leaps and bounds. But I argue this lightly because it detracts from my original question: Is fixed wireless the future of Google Fiber in SF? I'm not presupposing an answer, nor am I equipped to make a value judgement on said answer. Just curious & felt my parents' question deserved discussion, not downvotes.
