He concluded that readers should treat the novel as the last will and testament of ' Hiroshi Yamamoto, the hard sci-fi writer.' He stated, however, that he still deeply loves the novels' main character Piano, and is proud to have written such a charming character. He reckoned that while he could still write novels, writing 'hard sci-fi' (science-fiction stories based on scientific accuracy and achievable technology) novels, or novels that freely use math such as Project Piano, is now forever lost to him. While he is undergoing treatment, he noted that there are no signs of him getting better. However, Yamamoto concluded that he can no longer write works like this. Yamamoto recounted his love of the fanciful science fiction works of Murray Leinster, who dreamed up fantastical devices that could bend and break the limits of science to allow space travel or time travel, and even predicting a massive, Internet-like network of computers in his short story 'A Logic Named Joe.' Yet his memory remains intact, and he can even remember specific details of objects, places, and events that inspired scenes in Project Piano.

He compared himself to the final state of the character Charlie Gordon from the science-fiction story Flowers for Algernon.

Yamamoto stated in his afterword that he began suffering from cerebral infarction in 2014, and though he has recovered physically, his mental abilities for calculation and logic remain impaired, to the point that he has difficulty calculating addition of two-digit numbers. The stories that Ibis speaks of are the 7 novels about the events surrounding the announcements of the development of artificial intelligence (AI) in the 20th to 21st centuries.Publisher Hayakawa Shobo published on Thursday the afterword by Hiroshi Yamamoto in the new edition of his Project Piano novel, where Yamamoto revealed that he has been suffering from cerebral infarction, and enjoins readers to treat the novel as his 'last will and testament' as a 'hard sci-fi writer.' One day, he is abducted by Ibis, an android in the form of a young girl, and told of the stories created by humans in the ancient past. In this brutal time, our main character travels from colony to colony as a 'storyteller', one that speaks of the stories of the past. They resent the androids, who have built themselves a stable and cultural society. The story takes place centuries in the future, where the diminished populations of humans live uncultured lives in their own colonies. She tells him seven stories of human/android interaction in order to reveal the secret behind humanity's fall. In a world where humans are a minority and androids have created their own civilization, a wandering storyteller meets the beautiful android Ibis.
