Final answer:
In the future, people may be appalled by today's hunger, poverty, and unsustainable energy practices. Technological advancements and changes in identity, morality, and space exploration could make our current era seem quaint and limited by comparison.
Step-by-step explanation:
Imagining the world 100 years in the future, it's likely that future generations would be appalled by some of today’s beliefs and practices. For instance, the persistence of hunger, health crises, and poverty may seem particularly shocking, considering the technological advancements that allow for rapid global communication and travel. Additionally, our current heavy reliance on fossil fuels and lack of sustainable energy solutions could be viewed with disbelief, given the potential environmental consequences.
Concepts of identity and community might also dramatically change, and the idea of being bound by national borders or ethnic divisions could be viewed as outdated, as technology potentially creates a more interconnected global society. Further, our understanding of the universe and our approaches to morality might appear naive or simplistic to future societies that have advanced in both scientific knowledge and ethical complexity.
Last, the evolution of technology and space exploration, and its impact on the human species, may lead to a future where our descendants look back at the early 21st century as a quaint and limited era. Whether it's contemplating moving planets into different orbits or the potential spread of humanity to other stars, these grandiose ideas illustrate the significant changes in thinking that can happen over a century.
