I understand why certain tech companies such as Google/MSFT or chemical research companies like Pfizer or defense companies like Lockheed have quantum computers. Why are these being sold for personal use? Running Shor's algorithm probably gets boring after the second or third time. Plus, this machine simulates up to 8 qubits - what's the point of something that small?
