Again, the real world has already proven you wrong about this.

Multiple home gateways are being sold to people who know nothing about networking and yet are able to work with these 
gateways that divide their network up into multiple networks.

People are able to use mobile hotspot capability on their cell phones and tablets without a working understanding of 
networking.

More automation and improved software are being developed.

$40 routers (switches won't cut it here because switches don't cross network boundaries, as anyone with a working 
knowledge of networking would tell you) are already intelligent enough.

What you will find in the future (and are already starting to see today) is things like receivers acting as a router 
and front-ending an ether-over-HDMI network that interconnects certain capabilities on all of the attached AV 
components. These capabilities are only beginning to emerge, but they are being built into consumer goods already with 
IPv4 and will definitely see more complex more capable configurations in IPv6.

You will also see things like intelligent refrigerators acting as a router to front end the array of sensors and other 
connected devices in Pantries and small appliances.

You'll start seeing more and more things like smoke detectors and light bulbs that are IPv6 connected and/or 6LOWPAN 
attached. (Hint, NEST has already released an IPv4 smoke detector).

Do you really want your smoke detectors on the same network as your teenager's pr0n surfing?
