Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa
Questions include: Are we close to making face recognition a ubiquitous replacement for passwords in electronic systems that require a login, negating the need to remember and constantly change multiple passwords? - Can you describe the correlations among qubits, how they differ from ordinary bits and the potential advantage of them? - So perhaps a conscious observer is in fact the result of the underlying physical system building a model that averages out all the parallel threads into a coherent story? - What I don't really understand is destructive interference between threads of history. I understand how probabilities can add, but how can they interfere destructively? - Could our brains be a quantum computer? - It is, of a sort! A distinctive feature is it being inside your body and firing neurons in 3D spatial patterns. - What Wolfram Language functions would be most improved if they could utilize 20 million logical qubits on a quantum computer?
