Biotechnology and genetic engineering advance, potentially leading to the first gene-edited humans. - **2023 and Beyond:** - **Biological and Technological Convergence:** Humans might increasingly integrate technology into their bodies (cybernetic enhancements) for health, enhancement, or connectivity purposes. - **Advanced AI:** AI systems could become more autonomous and pervasive, potentially surpassing human intelligence in some areas. - **Space Exploration:** Human presence in space could expand, possibly including colonies on the Moon or Mars. - **Genetic Engineering:** Advances in this field could lead to significant increases in human lifespan, eradication of many genetic diseases, and perhaps even the creation of 'designer babies'. - **Societal Changes:** The blending of technology and biology could lead to new ethical, social, and political challenges.
