In the theoretical system of Ethical Literary Criticism,scientific selection,in some sense,is AI(Artificial Intelligence)phase,which is dominated by AIGC(Artificial Intelligence Generated Content).With the rapid development and wide availability of AI technology,AI literature has emerged as a new literature genre.AI literature is the literature generated by AI,that is,AIGC literature.By way of pre-training dataset and subsequent fine-tuning,AIGC acquires the ability to process natural language in an intelligent way,being capable of both imitating human beings in terms of composing poetry,novels,plays,stories,essays,and other literary texts analogous to traditional literature,and generating new literary texts in accordance with the AI era.Literary generation in the AI era is not limited to the generation of literary texts,but is now transforming into AIGC multi-modal literature and will foster the emergence of virtual AIGC digital writers.A type of simulated digital humans,simulated digital writers,supporting digital writers modeling based on collection and training,create simulated digital human images which not only have human-like body gestures and facial expressions but also endorse clothes and background shifting according to varied settings,adjustable voice access,motion,and expression drive.Simulated digital human is the update version of chatbots represented by ChatGPT.Classical writers can be resurrected with the help of AIGC,continuing their literary writing career.In the meantime,contemporary writers can clone themselves and create their own AI digital images by using the technology,generating a digital self and produce literary works of their own features.Inevitably,the advent of AIGC will trigger rumination and discussion about literary forms,literary contents,writers and works,reading and communication,theories and criticism,so as to promote changes of literary ideas and reconstruction of literary theories and criticism.
