Fiber is not dead. AT&T and VZ slowed their deployments, but they're both in the middle of upgrading their GPON network hardware and they'll be supporting what they still have. Their main obstacle to deploying more is that they're betting on 5G and wireless fixed access, and don't want to invest money in their wireline plant when they can invest that money in a network that supports both homes and mobile phones. Personally I think that wireless with never be as good as fixed, and it won't even be 'good enough' for the majority of users as 4k, VR, cloud-based everything starts becoming the norm.
AT&T and VZs competition which do not have a mobile network, Centurylink, Frontier, Windstream, and the cable companies, are cheerfully deploying GPON networks. There are also lots of small companies and municipal networks being built every day.
It's not going to happen overnight because of the cost, but it's happening and the US is actually well ahead of Europe when it comes to fiber. Europe is mostly betting on vectored VDSL2 and G.fast to get them through the next few years.
