Doe Quote by Edward Witten
“Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.”

Source Lecture or interview (unknown), null
Quantum mechanics introduced uncertainty, and string theory reintroduces fuzziness by replacing point particles with extended strings.
In simple terms: Uncertainty persists when moving from particles to strings.
Accept that fundamental physics may always retain inherent fuzziness.
