IPv6 is an excellent example of a solution that is computationally elegant to the point where it completely disregards the human interface component. Because of this, it has seen extremely slow adoption, and I believe it may never see full internal network adoption. I think most companies will eventually have IPv6 to their perimeter and do IPv4 internally with translation.

That right there outs you as a "never owned a Pixel" user. The pixel/nexus line has been some of the most long term supported phones in history. My wife had a Nexus 4 still getting updates when I owned my first Pixel. It's one of the major selling points that "justifies" it's price. That said, I recently tried a $200 nearly Android stock no-name phone from tmob the other day. Smart phone experience wise, it did match my $800 MSRP (not what I paid) Pixel 3. In every way except the camera. The camera blew. Made me really appreciate how amazing photos my Pixel takes, something more important now that we have our first child, who is now 2. So yeah, $200-$300 gets you a similar smartphone, but the additional $500 gets you one that takes pictures better than a cheap DSLR camera (especially when you don't know how to use an DSLR that well).
Dynamically binding, you realize the magic. Statically binding, you see only the hierarchy.
