I mean, maybe in the theoretical sense, but do conventional computers barely work in practice? Seems a bit of a pedantic argument. Gil Kalai and others with similar arguments play an important role in the QC community. They keep the rest of us honest and help point out the gaps. But I do think the ground they have to stand on is shrinking, and fast. Ultimately, they might still be right – that much is certain – but it seems to me that the strides being made in error correction, qubit design, qubit control, hardware architecture, and software are now pushing the field into an exponential scaling regime. To me, the big question is much less whether we'll get there, and much more "what will they be good for?"
