You must not be looking hard enough. There have been many accounts of 
how Dual Stack as a transition was steamrollered on over naysayers 
objections and predictions.

My personal correspondence on NANOG doesnt date that far back but here 
are some of the earliest on-topic examples readily available.

Depends on the definition of the goal. And your definition appears to be 
some measure of forward momentum. Certainly plenty exists. And that is 
good news in and of itself. But the internet needed more and long ago 
already. And that is the bad news.

When you build something and they dont come on schedule, you can blame 
them or you can consider what you could or should have done differently, 
especially as it may advise for the future. If you choose the former, 
there and then is the evidence of the type of thinking that tends to 
produce these outcomes.

Yeah, I think blaming bufferbloat is another example of designers 
passing the buck and engaging. If the reality consists of large buffers, 
start engineering with them in mind.

Or better yet, fast large ram cheaply and widely available should be 
considered a welcome and valuable resource. Try to make proper use of it.

As for the rest, false dichotomy again. Do both. Or applaud both. Or 
support both. Or at least, dont oppose either.
