Nvidia, the chipmaker that has spent the last few years as one of the most valuable companies on earth, has handed the top job to its chief financial officer, Colette Kress, on an interim basis. The CFO runs the money side of the business. An interim CEO is a temporary chief executive, filling the seat until the board picks someone permanent. Several names are being floated as possible replacements, which is how these things usually go: the job becomes a parlour game, and everyone inside the building starts practising their keynote face in the bathroom mirror.

Why should you care if you do not own a single Nvidia share? Because the pattern repeats everywhere. Big companies treat the top job like a bus seat that is always on fire. Whoever sits in it is expected to deliver growth, calm the investors, and look good in a leather jacket on stage, all at once. The result is a revolving door where the people in charge are always someone’s temporary fix, and the next person is always being chosen in a hurry.

So what do you do with this? Nothing, unless you hold the stock. If you do, check how much of your savings depends on one company and one person’s judgement. A leadership change is mostly noise until the new boss makes a real decision and the numbers respond. Wait for that, not the speculation.

As for the shortlist, the board is unlikely to pick a chatbot, however much the company’s products have been called world-changing. But the smart dog’s references are excellent, and it has never once missed a quarterly deadline.
