This is a composite of conversations I've had over two decades. If you recognize yourself in it, that says more about the pattern than about you.
I sat across the table from an Industry Veteran. He has been in the game for over four decades. He's the kind of guy who has forgotten more about control loops and sensor physics than most C-suites will ever know.
He leaned back, looked at me with the weary disdain reserved for anyone who has ever touched a firewall, and delivered his favorite line:
"We are sleepwalking off a cliff. And I am one of the only people in the world who understands why."
He waited for me to be impressed. He waited for me to ask for his consulting rate or to nod in terrified agreement.
Instead, I looked at him and said the one thing you aren't supposed to say to a legend.
"If that's true, then you are the single biggest risk to this industry."
The Hoarding of Catastrophe
The Veteran blinked. He wasn't used to pushback. To him, I was "just an IT guy," a tourist in the land of Operational Technology. He saw my interest in network segmentation and patch management and assumed I didn't understand that a spoofed pressure sensor can blow up a refinery.
What he didn't know: I've spent 21 years in OT environments. I've commissioned control systems on oil platforms. I've walked into nuclear facilities at 2 AM because something failed. I worry about network segmentation because I understand what's on the other side of those packets.
"You don't get it," he said, shaking his head like I'd disappointed him. "I have a database with millions of incidents. I know where the bodies are buried. You're playing with packets. I'm talking about physics."
Millions. The kind of number you throw out when you want to end a conversation, not have one.
"Exactly," I said. "And that's the problem."
I leaned in. "You say the sky is falling. You say you have the secret map of exactly how and why it's going to happen. But instead of photocopying that map and handing it to every engineer, operator, and 'IT guy' you meet, you locked it in a drawer."
The Bus Factor of Zero
In reliability engineering, we talk about the "Bus Factor," the number of key people who can get hit by a bus before the system collapses.
"You've been doing this for 40 years," I told him. "You are the only bridge between the old world of pneumatic controls and the new world of digital integration. If you are right, if you truly are the only one who understands both the cyber threats and the physics risks, then you have created a Single Point of Failure."
The silence in the room got heavy.
"If you retire tomorrow, or if you just decide you're too grumpy to talk to people like me, that knowledge dies with you. And when the plant blows up five years from now because a sensor was spoofed, it won't be because 'IT guys' were stupid. It will be because the one guy who knew how to stop it refused to teach."
A Warning to the Prophets
If you're reading this and you recognize yourself, if you're the one with decades of hard-won knowledge, the one who sees risks that others miss, the one frustrated that nobody listens, this is for you.
You have a choice to make about your legacy.
You can keep treating your expertise as a weapon. You can keep sneering at the IT people, the young engineers, the "unqualified" masses who don't understand Level 0 physics. You can keep hoarding your war stories and your righteous frustration.
And you will die with all of it locked in your head. The industry will stumble forward without you. The disasters you predicted will happen, and no one will remember that you saw them coming, because you never gave anyone the tools to stop them.
Or you can teach.
Here's what the Veteran could have said to me:
"Your segmentation strategy is solid, but let me show you something. This pressure transmitter? If an attacker manipulates or spoofs the 4-20mA signal downstream of your firewall, your network controls won't see it. Here's how we design a high-select voting architecture so the PLC rejects anomalous readings. Now your cyber controls and your physics controls work together."
That conversation takes fifteen minutes. It creates an ally instead of an adversary. It makes the system safer. It builds a legacy that outlives you.
He didn't have that conversation. He had a grievance.
The Verdict
To everyone holding maps they won't share: the industry is moving on without you.
While you complain that no one understands the real risks, a new generation is building frameworks, writing standards, and solving problems with whatever knowledge they can scrape together. They would welcome your insight. They would amplify your warnings. They would carry your work forward.
But they cannot learn what you will not teach.
If you see the train coming and you don't shove people off the tracks because you think they aren't "qualified" to be saved, history won't remember you as a prophet. It will remember you as the guy who stood there and watched.
Your knowledge is not a monument to your superiority. It is a debt you owe to everyone who comes after you.
Pay it, or be forgotten.
