Pretty sure CDNs will be around. The value add of a cdn isn't their cheaper commit rates. The value is in location diversity and capital investment in infrastructure and ports in those locations. In new speak CDNs are "bit delivery as a service". The customer pays a premium over raw transit to have the cdn make those capital & management investments.
Even for Netflix or another DIY delivery case a CDN will continue to have value. A couple cases immediately come to mind: Lower first byte latency on first video blocks, then a hinted handoff to the openconnect device. Resiliency/recovery of network events, in a similar manner. "long tail" content that doesn't fit in the open onnect cache width.
A key point of these devices is IIRC they're only available to peered ISPs in one those NA IXs. Netflix is essentially converting 5-8gbs of CDN/transit expense in to $50,000 (WAG) of capital. That's what's really brilliant to me.
