The Discipline of Saying What a Machine Cannot Do

There is a temptation, in a year this frightening, to want our machines to be more than they are — to hope the cold calculator in Singapore might also be a mind, that a reactor might be a rescue, that some threshold, once crossed, might carry us over the harder ones. The physicists spent this fortnight refusing that hope, and they were right to. A quantum processor factors and simulates; it does not know it is running, and it does not think. Our augmentations move faster than our review of them, and the honest answer about their newer tiers is that we do not yet know. This is not pessimism. It is the opposite: a civilization that lies to itself about what its tools can do will lean on them exactly where they will fail. The registered migrant count climbs past 120 million, and no clever machine subtracts a single person from that figure. The work of shelter, water and welcome remains stubbornly human. Better we admit it now, while admitting it still helps.
