I am of the opinion that a 100 Mbs network interface is sufficient. Do you have an example of streaming files that would ever even come close to exceeding the throughput of a 100 Mbps interface? 20Mbs seems to me more than sufficient to stream Netflix and Amazon UHD/HDR content.Agree wth everything you said. Especially when you count the fact that most consumer-y equipment (routers etc) will usually run at 50-70% (?) of their max rated capacity in a typical home network and you can start to get into trouble with a 100Mbps interface if you're trying to stream high bitrate files.
