To me, explaining this stuff is about trying to connect the technology with relatable human experience, and asserting/showing that the continued focus on throughput is misplaced. Is this audience already aware of that, or not? Maybe test them up front to see how much you need to talk about it. If you assume they know this and they don’t, the blank stares will start a minute or two into the talk...
If at least some people in the audience need an explanation, or even if you just want to hammer it home, for this type of crowd (should at least be somewhat technical), why not make an analogy with the “Megahertz myth <https://en.wikipedia.org/wiki/Megahertz_myth>”? That finally died in 2005 with the Pentium Extreme Edition (with the “Extreme” part not describing its speed, but rather its flirtation with thermal limits), when AMD came out with a “slower” CPU that was actually faster. Finally there was an awareness that ah, it’s not just clock speed, it’s pipelines, it’s caching, it’s branch prediction, it’s the instruction set, it’s…complicated, and there’s no getting around it.
Let’s start arguing that there’s an analogous “Megabit myth” that has no Wikipedia page yet because it persists to this day. Analogous to the megahertz myth, it’s not just “megabits per second”, but it’s inter-flow latency, it’s intra-flow latency, it’s fairness, it’s IPDV, it’s all of this under dynamic loads, it’s…complicated. And because it’s a complicated problem, Cake has a number of solutions built into it, which you’ll talk about... Perhaps Cake’s mascot should be a multi-headed creature of some kind (the monster that Eric referred to), maybe a hydra. Cake is definitely multi-headed. :)
If this audience is aware of this already, just move beyond it more quickly, but it’s worth hammering it home at least a bit, because again, where’s that "Megabit myth" Wikipedia page? It doesnt exist, because it hasn’t yet sunk in to the general consciousness that hey, why are we paying for 50Mbit symmetric fiber connections that can feel like 5Mbit ADSL?
Will the abandonment of network neutrality finally be the “Pentium Extreme Edition” that brings the megabit myth to a head?

I hadn’t noticed that complaint, but it’s legit. RRUL tests are interesting and point out what “should” happen, but long-term “before and after” tests on real networks and backhauls would be real proof. This doesn’t help you at this late stage in the game, but let’s take that comment to heart in the future. Meanwhile, do we have any quotes from users on how it improved their experience, or is that too anecdotal? or quotes from people in the field?

That’s a key question, you’ll probably have to feel the audience out unless someone knows the conference already?

Will do, or also write if you’re in need of something specific…
