What AI thinks a DBA does all day is a calm, orderly, deeply reassuring Tuesday. It has backups, documentation, proactive health checks, and apparently a door that closes. I asked. Then I wrote down my actual Tuesday. Its day has six items. Mine has thirteen.

I asked it to describe a typical day for a database administrator. It answered instantly, with the confidence of something that has never been cc’d.
One Tuesday, according to the job description and according to Tuesday.
| What AI Thinks Happens |
What Actually Happens |
| 9:00. Review overnight backup jobs and monitoring alerts. |
9:04. Somebody asks whether the database is slow. The database is not slow. Their Wi-Fi is slow. They remain unconvinced. Nobody has ever escalated a router. |
| 10:00. Analyse slow-running queries and optimise execution plans. |
9:20. A developer needs sysadmin. Just temporarily. Just for one thing. The one thing is all of them.
9:45. Meeting about a project that will not happen. We build a timeline anyway. By 10:25 it has a name, three owners and no future. |
| 11:30. Collaborate with development teams on schema design. |
10:30. The printer.
11:15. Somebody committed an UPDATE without a WHERE clause, with magnificent confidence. The confidence did not survive the row count. |
| 13:00. Capacity planning and index maintenance. |
12:00. A vendor asks me to disable a security setting. Their thirty-eight-page PDF calls this a documented requirement. Documented means typed.
13:30. Someone asks if I can just pull a quick report. Just means they have estimated my effort at zero. Quick means they want it before they finish asking. I ask what it is for. They say they will know when they see it. |
| 15:00. Update documentation and share knowledge with the team. |
14:00. Half an hour of genuine, uninterrupted database work. I look up and it is 14:12.
14:15. I raise a sandwich. A message arrives: “quick question.” It is a project wearing a question mark. I lower the sandwich.
15:00. I open the documentation to update it. The last edit is mine. It is from 2019. |
| 16:30. Proactive health checks and performance baselining. |
15:40. The same alert that has fired every Tuesday since 2021 fires again. Nobody will turn it off. Turning it off would mean knowing what it does. The alert has tenure.
16:50. I finally sit down to tune the query I have wanted to tune since Thursday.
16:53. The printer. It has sensed optimism. |
The left column has a rhythm. Tasks begin. Tasks end. Lunch appears to exist. The right column has an arrival rate. The sandwich is still on the desk.
One item did line up. Its 10:00 and my 16:50 are the same task. It allowed ninety minutes. I got three.

I would like to work in the left column. I meet every documented requirement. Please send me the application link.

I don’t know why. I never have. I’ve worked with databases for twenty years, and in every organisation there comes a quiet ceremonial moment when the printer becomes mine. No ticket assigns it. No manager announces it. The knowledge passes down like folklore, except folklore rarely needs a magenta cartridge. At one place I was shown the printer during the tour on my first morning. Nobody said what it was for. They just slowed down as we passed it.

I don’t print. There is a magenta cartridge in my laptop bag. I bought it myself. It was faster than explaining. It does not fit the current printer. I have not taken it out.
Why the Machine Missed the Printer
It wasn’t wrong, exactly. It was accurate to the job description. Every line of it appears in the posting that was written when the role was created, and in the training material, and in the certification syllabus, and in roughly four hundred thousand blog posts, several of them mine. I helped write the version of this job that does not have a printer in it. It read me. It believed me.
Almost none of my Tuesday is written down anywhere. Nobody wrote down that the printer is mine. Nobody wrote down which server you can restart quietly and which one has a person attached to it. Nobody wrote down that when a certain team says urgent they mean Thursday, and when a different team says whenever you get a chance they mean now. Knowing the difference is worth more than any certification I hold, and I hold a decorative number of them. That isn’t database administration. It is translation between local dialects of panic.
None of it’s in the training data, because none of it’s written down. And none of it’s written down because everybody already knows. Everybody means the five people who have been there long enough to stop asking why. The five people are the documentation. They have not been backed up.
Nobody writes down the parts of the job they’re still hoping are temporary. I have been hoping since 2006.
Then I Ran It Backwards
So I pasted my actual Tuesday in and asked it to write the job posting.
It did, immediately. It did not ask what it was for. The Wi-Fi argument became stakeholder communication. The sysadmin request became access governance. The meeting about the project that will not happen became cross-functional planning. The documentation I have not touched since 2019 became ongoing knowledge management. Every line was accurate. Not one of them was recognisable.
The printer did not appear. I looked twice. My Tuesday went in with a printer in it and came out clean.
It listed eight requirements. I meet six of them. They came from my own Tuesday.
Somebody’s real Tuesday went through this years before mine. What came out is the left column. The job description is not a fantasy. It is a real day with the printer taken out.
The Uncomfortable Half of the Joke
You could read that as good news. The machine can’t see the real job, so the real job is safe.
If your work is invisible to something that has read almost everything, it’s invisible to your HR system too. They’re all reading the same documented version of you. No appraisal has ever mentioned the printer. The documented version of you is the one applying for your next job. It interviews better.
The machine isn’t misunderstanding your job. It’s repeating back the only version of it anybody wrote down.
So write down the expensive parts. The judgement calls, the team translations, the seven undocumented things that only work because you know they do. Leave the printer for the oral tradition.
I went back and asked whether a DBA is ever responsible for office printers. I described it. I typed the question standing at the printer.
It said no. It said that would fall outside the typical scope of the role.
It sounded so certain. I didn’t correct it. One of us should have boundaries, and apparently it is the machine.
This is the same argument sitting underneath all thirty essays in my book AI: Nobody’s in There. But we’re still in here. All thirty are free to read at pinaldave.com, and the book is available in paperback, Kindle and audiobook on Amazon.

The machine did not get my job wrong. It read the job description. The funny part is everything the job description forgot. The dangerous part is that everybody else reads the same one. The printer is not mine.
