Your engineers hold the content AI cannot write

The most valuable content input in your business is sitting in the head of whoever answers the hard technical questions, and getting it out costs 30 minutes of their time.

This is not a motivational point about subject matter experts. It is a supply point. Every business now has effectively unlimited access to generic explanation, which means generic explanation has a market value of about zero. What remains scarce is the thing that only exists because someone did the work: the number from your own jobs, the objection you have answered four hundred times, the reason the obvious specification is wrong on that particular site.

Your experts will not write it down. Stop asking them to.

Why writing assignments fail

Ask a structural engineer to write a 900-word article and three things happen. It sits in their inbox for six weeks. When it arrives it is either four dense paragraphs of standards references or a page of hedged generalities, because writing for an unknown audience is a specialist skill and they do not have it. Then someone edits the specificity out to make it read nicely, which removes the only part worth publishing.

Ask the same person a question out loud and they answer it in ninety seconds, precisely, with an example. The knowledge is not the constraint. The format is.

So change the format. Record the conversation, and treat writing as a transcription and structuring job done by someone else.

The interview that produces publishable material

Thirty minutes. Recorded, with permission. One interviewer who has done ten minutes of preparation. No slides, no agenda document, no request for them to prepare anything, because preparation makes people revert to brochure language.

Six questions, in this order, and follow every one with a request for an example.

What do clients get wrong about this before they talk to us? This produces the objections and the misconceptions, which is the highest-converting content you will ever publish.

What is the question you answer most often? Ask for the actual wording people use. That wording is your heading.

What number do you use when you are estimating this in your head? Experts carry rules of thumb they never write down. Cost per square metre, hours per unit, typical lead time, failure rate, the threshold above which the cheap option stops working. Gold.

Where does the standard advice break? The conditions under which the normal answer is wrong. This is the non-obvious content nobody else has.

Tell me about a job where this went sideways. One story, with what it cost and what changed afterwards.

What would you tell someone to check before they call us? The useful-without-us test, answered by the person who would know.

Then stop. Do not run to sixty minutes. The last twenty are always worse than the first twenty.

Turning 30 minutes into three months of material

One good interview yields more than one article. From a single 30-minute recording you should get a long-form page built around the two or three strongest sub-questions, four to six short social posts each carrying one specific claim, three or four FAQ entries in the expert's own words, and a set of quoted lines the sales team can use verbatim in email.

Keep their phrasing. When an engineer says the slab tells you before the wall does, do not translate it into a sentence about early structural indicators being present at slab level. The first one is memorable, quotable and true to how the trade talks. The second is the reason your content sounds like everyone else's.

Research on AI writing assistants presented at CHI 2025 found they homogenise writing toward a single register and strip cultural nuance. That is the practical failure mode of drafting content without a source recording. It is not that the facts come out wrong. It is that the voice, the specificity and the local register come out sanded flat, and those were the parts doing the work.

The cost of the alternative

There is a measurable price for content produced without a real input. Research from BetterUp Labs and Stanford Social Media Lab, published in HBR in September 2025 with 1,150 US desk workers, measured what they called workslop: output that looks like work but does not advance the task. Forty per cent of respondents had received it in the previous month. Each instance cost the receiving colleague one hour and fifty six minutes, working out to roughly $186 per employee each month. At 10,000 staff that is about $9 million a year.

Marketing produces a version of this constantly. The article that was generated from nothing, edited by someone with no domain knowledge, reviewed by a technical lead who has to reconstruct what it should have said, and published to no effect. The interview-first model removes the reconstruction step, which is where the cost sits.

Making it stick operationally

Book it as a recurring 30-minute slot, not a request. Fortnightly with a rotating expert works. A calendar hold gets honoured, an email asking for content does not.

Send one question in advance, never all six, so they arrive thinking rather than scripted.

Do the accuracy check in tracked changes with an explicit brief: correct anything factually wrong, leave the wording alone. Without that instruction, technical reviewers rewrite for tone and you lose the voice you went there to get.

Publish the transcript-derived FAQ answers as well as the polished article. Both are retrievable, and the raw answers often read better.

Where it does not work

It fails when the expert genuinely has nothing distinctive to say, which happens in commoditised service lines and is worth knowing early.

It fails when compliance requires every published claim to be signed off by three people, because the specificity dies in the third review.

And it fails if you interview the wrong person. Sales leaders give you positioning. Delivery leads give you facts. Interview the person who does the work, not the person who sells it.

Half an hour, recorded. That is the entire input cost of the only content on your site that could not have been written without you.
