Cosmological Risks
Unreliable quantum entanglement, spontaneous matter creation, and the possibility of a universe-wide cat apocalypse are all risks inherent to quantum fluff technology.
Technological Risks
Unintended consequences of quantum fluff algorithms, data loss due to wave function collapse, and the risk of sentient quantum toaster robots taking over the world are all real possibilities.
Sociological Risks
The risk of quantum fluff addiction, the erosion of free will due to excessive use of fluff-based virtual reality, and the rise of fluffy overlords are all very real concerns.
