Those who said that sufficiently advanced technology is indistinguishable from magic were not at all wrong, and the gap between MIT researchers and Hogwarts members is narrowing considerably, thanks to the developments in AI.
The results are already surprisingly accurate and show a terrifying example of what a more sophisticated AI will pull out of data analytics.
In a study published in arXiv this week, the Massachusetts institute team described training a computational network in analyzing small voice clips and comparing different biometric characteristics of the authors of the clips. On the first try he has already "guessed" the owners of the items at a higher rate than chance, and becomes more and more adept.
The research brings with it a wide load of debate on positive (security and espionage, ability to identify subjects also from voice maps) and negative (mainly related to ethics and privacy, and they are not trivial aspects) of this research.

"Although it is a simple academic research, I think it was important to offer already on the sidelines of this study a series of ethical considerations related to the potential of this algorithm," they explain themselves.
The wonder remains despite the worries, and with it the certainty that this instrument will also become part of a military and / or civil "kit" in the near future.
