The danger has been there the whole time. Now someone is holding the flashlight.

Many client boards I deal with ask their Gen Z grandkids to explain the latest tech. Which is a serious and immediate problem, because something happened in AI last week that boards really do need to understand — and there is a real danger the grown-up version of the story will not get through.

This is a fourteen-year-old’s version. It landed for me immediately. Read on.

Imagine the world’s computers are giant Lego castles — your phone, your laptop, the servers that run your bank, your hospital, your kid’s school. Millions of tiny bricks. Those bricks are computer code. Every castle has weak spots. Bricks that do not click in right. Bricks that are loose. Bricks that are broken. Hidden for years. Some for decades.

Here is what just happened. An AI company you may have heard of, called Anthropic, built a special “magic flashlight” called Mythos. And Mythos can look at a Lego castle and see every weak brick, every broken brick, and how to use them to sneak in and cause mayhem.

The flashlight was pointed at the biggest computer systems on Earth and found thousands of damaged bricks. Including ones that experts had been staring at for decades and completely missed.

Now here is the bit that is worrying grown-ups. And rightly so. Someone has a Mythos, a magic flashlight. It shines on every weak brick in every castle in the world. Give it to the right people and they can fix the weak spots. Fix the broken bricks. Give it to the wrong people, they find the holes, walk into the castle, and take what they want. Anywhere, anytime.

So Anthropic decided not to let everyone use Mythos. They handed it to a small group — Apple, Google, Microsoft and a handful of others — on the condition they use it to fix things, not break them.

Why this is mad important

We know other AI companies are six to eighteen months away from building their own version of Mythos, their own magic flashlight. But if those magic flashlights get into the wrong hands, they can wreak havoc.

The weak bricks have been there the whole time. The difference is that now, somebody is holding the flashlight — and soon, everyone will have one. The good guys, and the bad guys.

Drop the Lego for a moment. When the bad guys walk into your castle, they do not break things. They sit quietly in your hall for months, reading your mail and watching your every move. They take your customer list. They steal your secrets. They lock your front door from the inside and demand a ransom to open it. One Monday morning, you will find out.

The question to ask this month

I shared this story with a board chair. I watched the penny drop. He got it. Ask your management team this month: “Do we really know where all our broken bricks are, and how fast can we fix them?”
