The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.

La última pregunta, una obra maestra de la ciencia ficción, es, tal y como afirmó su autor en repetidas ocasiones, por encima de toda duda, mi favorita entre todas las historias que he escrito en mi carrera. ¿Es posible revertir el inevitable final del Universo, o el mundo debe acabar de todas formas? es la pregunta que desde un día del siglo XXI, hasta generaciones y generaciones posteriores en el tiempo, hacen los humanos a los ordenadores.

Un clásico entre los clásicos de la ciencia ficción. Esta historia, que apareció por primera vez en 1976, fue mi exposición más clarividente del desarrollo de los robots. Trataba del deseo de un robot de convertirse en hombre y la forma en que realizaba este deseo, paso a paso. No tenía intención de escribir esta historia cuando la empecé, se escribió sola, y se trazó y entrelazó en la máquina de escribir. Acabó siendo la tercera de mis historias favoritas, entre todas las escritas.
