The Indus Valley script remains one of the greatest enigmas of archaeology. For more than a century, thousands of inscriptions on seals and tablets have resisted all attempts at decipherment. What artificial intelligence is starting to show is not a literal translation, but a disturbing pattern: symbols appear to behave more like a structured sign system than conventional human language.
What we know so far
Advanced Civilization: Between 2600 and 1900 BC, the Indus Valley (present-day Pakistan and India) had planned cities such as Mohenjo-Daro and Harappa, with drainage, standardized trade, and uniform weights.
Indecipherable writing: More than 500 symbols have been found, but there is no bilingual text (like the Rosetta Stone for hieroglyphs) that allows comparisons.
AI in action: Machine learning algorithms are analyzing the frequency and sequence of signs. The results suggest that they do not follow the typical rules of a phonetic language, but could be a notation system, perhaps administrative or ritual.
Why is it disturbing?
If not a human language, the Indus script could be a symbolic code used for commerce, religion, or social control.
This would imply that one of the greatest civilizations of antiquity did not leave a written language as such, but rather a recording system.
It changes the way we understand cultural transmission: perhaps oral communication was dominant and symbols were only auxiliary.
The open debate
Some experts believe that AI is revealing that the Indus script was never a complete language, but rather a system of functional symbols. Others maintain that it could still be a lost language, but with a structure radically different from the known ones.
