"Posthuman" refers to a concept in philosophy and cultural studies that explores the idea of a future where humans evolve beyond their current physical and mental limitations. This evolution may involve advanced technology, genetic engineering, or artificial intelligence, leading to new forms of existence that challenge traditional notions of what it means to be human. The term is often associated with discussions about transhumanism, which advocates for the enhancement of the human condition through technology. It also raises ethical questions about identity, consciousness, and the implications of merging human and machine, as seen in works by authors like Donna Haraway and Nick Bostrom.
