For the first time, during a test created in 1950, an artificial intelligence managed to appear more human than humans themselves.
There were people swearing that the AI ​​was a person, while real humans were passed off as robots.
If you haven't been scared yet, now is the time.
- 🧠The test that separates man from machine
In 1950, Alan Turing created a challenge: if an AI can talk like a human to the point of deceiving the person on the other end, it would get approval.
It's the famous Turing Test.
Until today, no AI had gotten there, until GPT-4.5 came along.
- 🧪 The most daring experiment so far
Researchers at the University of California gathered 300 people.
Each one was talking, at the same time, with:
•a human
•an AI (GPT-4.5)
In the end, they had to say: “who was the human?”
The result will blow your mind (!)
- 🎠The AI ​​pretended to be human — and fooled everyone
When GPT-4.5 assumed a specific persona (such as a young pop culture fan), it was identified as human 73% of the time.
The weirdest?
Humans themselves were only identified in 67%.
In other words: the AI ​​was more convincing as a human… than real humans.
- 🧊 No character, AI looks like robot again
When GPT-4.5 spoke “out of character,” its accuracy rate dropped to 36%.
GPT-4o, the newest version, was even worse: 21%.
The secret of AI? It's not thinking. It is to interpret.
- 🤔 So the AI ​​understands what it says?
No. She doesn't understand anything.
It just imitates language patterns based on billions of examples.
But he imitates so well that he deceives.
And that changes everything: customer service, sales, politics, fake news, scams…
- ⚠️ The boundary between man and machine is blurring
If an AI can already fool you in a bar conversation…
Imagine a sales call, a job interview or a business negotiation?
The difference between a real person and a simulation is becoming increasingly subtle.
- 🧨 The scientists' warning is categorical
They are not saying that AI understands the world.
But be warned: these models are still “raw”.
And they are already more convincing than most people.
What happens when they get really good?
