The future of GPU is virtualization (ie where a single gpu can power multiple VMs at almost native performance). When the mining profits start to dwindle, AMD is going to need something to fall back on. They should start putting MxGPU on their consumer cards. Intel already sees the future and has enabled GVT-g on all their integrated GPUs.

AMD had slideshows describing the feature on the new Vegas, but decided to disable it before release. This alone stopped me from building a threadripper + vega machine. Now instead I'm waiting for Intel to add more cores, then I will use their integrated graphics between multiple VMs.
