Conference Keynotes Are Theatre: The Attendee List Is the Product
I go to conferences. I keep going. I have booked flights for them, expensed hotels for them, and I will do it again this autumn, so nothing that follows is an argument for staying home.
What I've stopped doing is pretending the sessions are why I went.
The keynote is theatre. Not a bad keynote, not an unusually promotional one, but the format itself. A person walks on stage and, over forty-five minutes, delivers information you could have absorbed in four minutes of reading. The slides go up afterwards. Frequently the whole thing is on video within a week. You paid two thousand dollars and gave up three days to watch a press release performed live.
Run the test. Pick any conference you attended in the last two years and name one thing you learned in a session that changed what you did afterwards. Not something you found interesting. Something that changed a decision. Most people, honestly asked, come up with nothing, and then start talking about a conversation they had in a corridor.
That answer is the whole argument. The corridor is the product. The stage is the excuse for building the corridor.
The stage is a channel with terrible bandwidth
Consider what a keynote actually is as an information channel. It's linear, so you can't skip the part you already know. It's synchronous, so you can't pause to check a claim. It has no search. It runs at speaking pace, which is roughly a third of reading pace. And it's optimised for a room of several hundred people with wildly different backgrounds, which means it's calibrated to the least informed person present.
Now consider who the speaker is. Someone whose company paid for the slot, or whose company sponsors the event, or who is presenting a product roadmap they need customers to believe in. The incentive to say anything genuinely surprising on stage is close to zero, because the downside of a quotable mistake is enormous and the upside of a quotable insight accrues mostly to a competitor's analyst.
So you have a low-bandwidth channel carrying content that has been deliberately de-risked. The organisers know this. That's why the good ones spend their money on floor space and evening events rather than on speakers.
What you can only get by being there
Here's the part that justifies the flight.
The exhibition floor, worked properly, is a field survey. You are standing in a room containing most of an industry's suppliers, each with a booth staffed by engineers who will answer specific questions about their product because that is literally their job that week. Ask a vendor's field applications engineer what their customers are actually asking for and you will get an honest answer, because they are proud of knowing it and because nobody has media-trained them.
Booth sizes are a balance sheet you can read by walking. A company that took forty square metres last year and nine this year has told you something their earnings call did not. So has the company that sent twelve people to a show where they have no product to launch.
And the attendee list, where you can get one, is the single most valuable document produced by any conference. It tells you which companies consider this space worth the travel budget, which functions they sent, and at what seniority. Procurement people showing up in numbers at a technical conference means purchasing decisions are close. That is a signal you cannot buy from a research firm at any price, and it is sitting in the registration app.
Why the format survives anyway
Because it works as a coordination mechanism, not as an information channel.
Getting four hundred people from thirty companies into one city on the same three days is genuinely hard, and the keynote schedule is the fiction that makes it happen. Nobody can justify a flight to have eleven unstructured conversations. Everybody can justify a flight to attend a conference. The programme exists to make the calendar entry defensible.
Once you see it that way, the sessions stop being disappointing and start being useful in a different sense. They are a schelling point. They tell you where people will be and when they will be free, which is what you actually needed.
What I still concede
There is a category of session that isn't theatre, and I don't want to lose it in the argument.
Peer-reviewed technical conferences are a publication venue. The paper is the artefact, the presentation is a summary of it, and the question period afterwards is real. When someone stands up at a device conference and asks the presenter about a measurement condition buried in the fourth figure, that exchange is not available in the proceedings and it is often the most informative ninety seconds of the day. The same goes for genuine panels where the participants disagree, and for tutorials taught by people who teach for a living.
What those have in common is that the speaker is exposed. Somebody in the room can contradict them with evidence, in public, immediately. Where that exposure exists, the format earns its place.
Where it doesn't, you're watching a play. Enjoy it if you like. Just don't put it in the trip report.
