Nas bolsas americanas de quinta-feira, a confiança cedeu lugar ao receio: não o medo de que a inteligência artificial falhe, mas o de que triunfe de forma demasiado abrangente. Os três principais índices recuaram entre 1,3% e 2%, enquanto os investidores começaram a questionar se setores inteiros — seguros, gestão de patrimónios, imobiliário, software — sobreviverão a uma tecnologia que promete fazer o mesmo trabalho mais barato e mais depressa. É o momento em que uma narrativa de progresso se dobra sobre si mesma e revela a sua sombra.
