It could be 'five to ten years' before the world finally drags itself away from IPv4

Re: That's pretty much all it does

Um, not really.

IPV4 with two more octets would have met the need for more space admirably, and address representations would still be human sized. Job done in six months, hardware manufacturers could have had samples out in a few more, and we could be using it.

Instead of which, we got a weird-ass new addressing scheme which is not sysadmin friendly at all, and the names of most of the supporting protocols changed as well, merely for the sheer love of being dicks. (And because of a truly, horribly mistaken belief that every endpoint should be publically visible on the internet to every other. NAT: it ain't a kludge, it's a vital security tool.)

Rule of a million

Back in the day when I was doing this stuff , I applied a rule of thumb that I called the rule of a million

Does it run a million times a year, or does it use more than a million CPU seconds when our largest client runs it? Optimise.

The rule of a million stood next to the rule of three: if I can't think of three qualitatively different ways to solve a problem, I don't understand the problem. More investigation required.

(The latter rule almost always led to me using the fifth or sixth approach that I thought of. Think of two ways, others are hard to see. Three, it gets easier.)
