Why quantum computing is Not a threat to bitcoin: Historically, hundreds of computing systems have been proposed or built: Mechanical Analog electrical Optical / wave-based Magnetic / spin-based Chemical Biological (DNA, wetware) Neuromorphic Quantum Fluidic Other than digital they share the same issue scaling/error correction: Error increases with size Noise accumulates Physical coupling worsens Precision degrades Continuous physics compounds instability. As digital systems scale, errors can decrease rather than increase. Digital computing is the only architecture so far proven to do this. With every quantum computing "success".. The quantum system increasingly resembles a classical digital computer, taking on aspects of the digital computer to achieve a new "groundbreaking result". Including google new headlines. Hundreds of computing paradigms exist. Only digital computation has demonstrated sustained error suppression with scale. Quantum computing’s progress reinforces this rather than contradicting it. You can imagine it as an, inverse 3D bell curve. The most stable position is the base, which represents digital computers. All other forms exist at some non-scalable higher point. If you want any of them to scale, the process will eventually push it into the base—digital computing. #ideas #Quantum
