Leonardo & Cookie Monster

A long time ago, somewhere in the 1980s, I was on holiday in Italy with my parents. We visited many places, including Padua. There, we wanted to see an ancient university building, but it was just closing. The friendly caretaker gestured that we were welcome to accompany him on his locking-up round. And so it happened that, moments later, we found ourselves standing at the lectern of Leonardo da Vinci.

Have you ever been somewhere where it felt like you weren’t really supposed to be there, yet the moment felt magical? That’s how it felt back then, and I felt it again this week, when I went to get a cup of hot water for tea at the office. The machine showed a red bar. Not a good sign. The screen no longer displayed the usual options for every imaginable type of coffee, but choices such as ‘remote-controlled measures’ and ‘ingredient management’. And in the top left corner was the most important label of all: ‘machine administrator’. With, right next to it, a ‘log out’ icon. So yes, we were logged in as administrator.

Let me speculate for a moment about what might have happened here. The machine had a malfunction, as evidenced by the red light (on the adjacent machine, that bar glowed white). A maintenance engineer had been called in, but couldn’t immediately fix the problem. For a moment it looked as if various things simply needed refilling, but there was more going on; the bottom message on the display read ‘middle grinder empty’, yet that container was absolutely brimming with coffee beans. So the engineer must have left to fetch spare parts, and forgot to log out.

Colleagues from my meeting stood there, grinning. Stumbling into something like this while a security officer happened to be visiting – well, that was rather perfect. I see this more often: people smile sheepishly, feeling a kind of second-hand embarrassment. Someone hasn’t followed the rules and a security officer has caught them red-handed. Oops. Here comes trouble!

Coffee machines fall well outside my official jurisdiction, but I can of course use this example to highlight the broader issue. And that issue isn’t so much that people occasionally forget to lock their workstation – you get that, don’t you – but rather the more general picture that security isn’t always top of mind. When it really should be.

Recently, I was in a discussion about AI. It was about how you’re not allowed to include personal data in your prompts; for example, you can’t just paste in an entire letter and ask the system to analyse it. A manager said that one of his employees had approached him with a brilliant idea: ‘I’ll just ask AI to remove the personal data first!’ The employee was sent away with the instruction to think very carefully about what he had just said. Hopefully by now he has realised that you shouldn’t ask Cookie Monster to keep the cookies safe before washing the cookie jar.

Look, I understand that you don’t share my professional deformation of seeing risks everywhere. But surely a certain level of basic hygiene is not too much to expect, right? You don’t have to be a Leonardo, but don’t be a Cookie Monster either.

 

And in de big bad world…
