The Lock is Already Broken

You think your data is safe. You think encryption is a shield.
It’s not. It’s a time capsule.
For many, time already ran out.

We are asleep.
The consequences? For some, humiliation.
For others, prosecution before the tribunal.

We see the small “lock” icon in our browser and feel safe.
We use complex passwords.
We trust encryption.
We believe our secrets are ours.

Think twice. That belief is a fantasy.

For years, we’ve been told to guard against breaches.
We were told to look for a broken window.
But we should have been looking at the foundation.

The foundation of our digital trust is cracked.
This isn’t speculation.
The powers we once feared — quantum computing and advanced AI — are here.
States are already turning them into weapons. Soon, corporations and hackers will follow.

The Quiet Catastrophe

You didn’t hear about it on the news.
I didn’t either.
It didn’t look like an explosion.
But it is happening behind closed doors.

Think of Helios Corp.

Three weeks ago, they led the market.
Their crown jewel was Project Solara, a breakthrough solar formula.
Heavily encrypted. Or so they thought.

Last week, a rival published it.
Their stock collapsed overnight.

No breach. No insider. No alarm.
The files were encrypted. Useless to anyone.

Yet the data was read.

How?

A year ago, it began. The files were taken.
At the time, they were just encrypted noise.

Then a quantum computer solved them — in minutes.

The lock didn’t break.
It dissolved.

The waiting is over.

This is the new reality: “Harvest Now, Decrypt Later” (HNDL).
And the “later” has arrived.

For years, state actors, East and West, have been quietly collecting:

  • Corporate research
  • Diplomatic cables
  • Medical and personal data

They waited for this moment.
Now the keys exist.
Everything once “secure” is readable now.

The Hunter in the Code

Zero-day vulnerabilities once required teams of brilliant analysts.
Now imagine intelligence that never sleeps, never doubts, never questions.

Not your everyday friendly chatbot.
A Predator — cloaked, patient, and merciless.
If you’ve seen Predator (1987), you know the feeling.

Combine that predator-level AI with quantum processing, and you get something terrifying:

  • It doesn’t just scan for flaws. It understands code.
  • It explores billions of possibilities at once.
  • It finds a tiny flaw — and exploits it in silence.

A quantum–AI hybrid could breach a power grid, craft its own malware, and vanish before you finish your morning coffee.

The Delusion of Safety

The threat isn’t that your data might be stolen.
It’s that your identity might already be copied.

It’s not that a system might fail.
It’s that its logic might already be rewritten.

We’ve built our digital world on quicksand — and we still call it a fortress.

The time to wake up was five years ago.
The next best time is now.

The Only Way Forward

There is a bit of good news.
The “good guys” are building new locks — Post-Quantum Cryptography (PQC).
It’s made for this new age of hybrid quantum-AI threats.

But a shield left on the wall protects no one.

It’s up to us to act. All of us.
Audit what you store.
Encrypt with PQC-ready systems.
And for anything critical, keep backups offline.

Because the silence you hear isn’t peace.
It’s someone, somewhere, reading your mail.

Knives and Robots: Tools of Progress, Shadows of the Past

A chef might say: “Give me a knife, and I can create tasty dishes.”
A technologist might say: “Give me a robot, and I will ease your life.”

Noble and true statements. But have you ever asked yourself what a knife and a robot have in common?

At first glance, you might say: nothing. But from a historical perspective, these tools share remarkable parallels. Both represent humanity’s ingenuity and the dual capacity to create and destroy.

Humanity’s Oldest Tool – the Knife

The knife is one of the oldest tools in human history, with origins in the Paleolithic era. Early humans shaped stones into crude cutting implements, a leap that revolutionized survival. By the Bronze Age, knives evolved with the introduction of metals like copper and bronze, offering sharper and more durable blades. The Iron Age brought further refinement, as iron and steel allowed for stronger, more versatile designs that continue to be essential today.

Initially a tool of survival, the knife became a weapon. Its evolution from necessity to an instrument of war underscores its dual role as both a creator of life and an executioner of death.

A Dream of Artificial Helpers – the Robot

The concept of robots traces back to ancient myths and early mechanical devices. Greek mythology spoke of Talos, a giant automaton built by Hephaestus, while similar beings appeared in Chinese and Indian stories. Practical attempts to build robotic creations began as early as the 3rd century BCE (a bit less than 2300 years ago), with inventors like Ctesibius and Hero of Alexandria crafting water- and air-powered automata for entertainment.

The Renaissance saw breakthroughs, with Leonardo da Vinci designing a mechanical knight in the 15th century. By the 18th century, automata like Jacques de Vaucanson’s digesting duck demonstrated the fusion of artistry and engineering.

Modern robotics took shape during the Industrial Revolution, driven by advancements in mechanics and electricity. The term “robot” was coined in 1921 by Czech playwright Karel Čapek in R.U.R. (Rossum’s Universal Robots). In 1954, George Devol created the first programmable robot, Unimate, marking a milestone in manufacturing automation.

Today, robots play diverse roles in industries, healthcare, and homes, showcasing humanity’s aspiration to mimic life and enhance productivity, as evidenced by examples we already see, particularly in China and the USA.

The Dark Side of Innovation

Despite their contributions to progress, knives and robots also reveal humanity’s darker tendencies. Just as knives transitioned from tools to weapons, robots are increasingly being developed for military purposes. Governments worldwide, bypassing their own ethical frameworks, are pouring vast resources into creating robotic weapons powered by artificial intelligence (AI), mirroring the historical trajectory of knives becoming swords.

What makes our era especially concerning is easy accessibility. Unlike the past, when such technologies required massive industrial complexes, today’s advancements in AI and robotics can be achieved with modest local datacenters.

Yet, the real threat does not lie with small-scale innovators but with governments – entities that have historically driven wars against the will of their own citizens.

A Call for Accountability

Should we stop the development of robotics and artificial intelligence? Certainly not. These technologies save countless lives, from assisting the elderly to providing critical healthcare. However, the lessons of history urge us to act responsibly, something governments are often willing to overlook.

Today, we have tools unavailable in the past, such as legal systems, public accountability, and the power of collective voice. Citizens must demand transparency and ethics in AI and robotics development. Laws must be created and enforced to ensure these tools serve humanity’s survival, not its destruction.

The Choice Is Ours

Knives and robots are mirrors of our potential – symbols of creativity and destruction. Their impact depends not on their existence but on how we choose to handle them.

By addressing the political and ethical dimensions of technology, we can ensure that these tools remain blessings rather than curses. After all, progress is not just about invention – it’s about responsibility.

Do You Know How to Use AI or a Chatbot in Your Daily Life?

Here’s a simple but effective guide:

Assign the AI a Role

Begin by designating the AI a specific role, such as a computer expert, a Microsoft Windows or Linux specialist, or even a cooking chef.

Prompt Examples:

Prompt 1 – Assign a Role to the AI:
“You are an Italian cooking chef.” Press ENTER.

Prompt 2 – Modify a Recipe:
“I have visitors tonight, and I need to cook for 10 people. I was planning to make a homemade pasta dish with walnut sauce a creamy sauce made from walnuts, garlic, olive oil, and Parmesan cheese. However, one of the guests is allergic to walnuts. Can you suggest a way to adapt the recipe to exclude the nuts while preserving the original flavor profile as much as possible?” Press ENTER.

Prompt 3 – Request a List of Ingredients:
“Can you provide a list of ingredients for a nut-free alternative to my original recipe?” Press ENTER.

Be as Specific as Possible

Avoid vague or overly general prompts like:

  • “I need to cook something for my visitors.”
    With such prompts, the AI might suggest any random recipe, even one from 200 years ago.

Likewise, avoid generic technical descriptions like:

  • “I have a problem with my computer.”
    The response will likely be too broad to solve your issue.

Provide Context and Detail

Let’s refine the process with a technical example:

Example: Computer Problem

Prompt 1 – Assign a Role:
“You are now an expert in Windows 10 Pro.”
Press ENTER.

Prompt 2 – Describe the issue with relevant details (be as specific as possible):
“I’m encountering an issue in Office Excel. When I try to create a table that summarizes my sales data, I get an error that says: ‘Something went wrong with the table.’ My table just has columns for ‘Product,’ ‘Sales,’ and ‘Date.’ Can you help me figure out what’s causing this and how I can fix it?”
Press ENTER.

Example: Troubleshooting a Smartphone Issue

Prompt 1 – Assign a Role:
“You are now an Android (or Apple) smartphone expert.”
Press ENTER.

Prompt 2 – Describe the Issue with Relevant Details:
“My phone keeps freezing when I try to open the camera app. It worked fine last week, but now it stops responding and the screen goes black. I’ve tried restarting my phone, but it still happens. Can you help me fix this?”
Press ENTER.

Why Details Matter

Including precise details helps the AI provide targeted and useful answers.

For the cooking example, specifying the dish and the ingredients allows the AI to offer an appropriate substitute.

For the technical example, describing the application, version, and error message enables the AI to diagnose the problem more effectively.

Privacy Considerations and Confidentiality

NEVER share private or enterprise-sensitive data. Instead, use substitute data or anonymize information. Remember, these interactions may be used for training purposes and could potentially be visible to others.

Practical Tips for Using AI

Keep the Chat Open
Many enterprise chatbots operate in a “private” mode. If you close the chat window too early, you might lose the session’s context and need to restart from scratch.

Save History
If possible, save the chat history for future reference, especially for ongoing issues or projects – some AI offer an ‘Export’ tool (use it).

By following these steps, you can effectively use AI to solve everyday problems, whether it’s planning a meal or troubleshooting software issues. Stay specific, provide context, and protect your privacy for the best results!
