In The Lord of the Rings, the palantír allows its user to see everything, but at a great cost: loss of control and manipulation. Palantir Technologies echoes this idea in the real world.
By aggregating massive amounts of data, Palantir provides governments and intelligence agencies with extraordinary surveillance and analytical power. While effective for security and intelligence, this concentration of data poses serious risks to privacy, transparency, and individual freedom.
As Tolkien warned, great vision without limits can be dangerous especially when few control what is seen.
