Who is going to check their answer to make sure that it’s right?
And another but: Quantum computers are still a long way from being ready for mainstream use. The machines are notoriously prone to errors, because even the slightest change in temperature or tiny vibration can destroy the delicate state of qubits. Researchers are working on machines that will be easier to build, manage, and scale, and some computers are now available via the computing cloud. But it could still be many years before quantum computers that can tackle a wide range of problems are widely available.
Not sure, guess we will find out in 10000 years
Something fun to listen to while you wait
