If that robot had figured out that I was a person, not a chair, and that I was willing to get out of its way if it was trying to get somewhere, then it actually would have been more efficient at getting its job done if it had bothered to notice that I was a human and that I have different affordances than things like chairs and walls do.
Se ele soubesse que eu era uma pessoa e não uma cadeira, e que eu sairia do caminho se ele tentasse chegar a algum lugar, a tarefa dele teria sido mais eficiente se tivesse notado que eu era humana e tinha capacidades diferentes de uma cadeira ou uma parede.
