Humans have achieved a lot since they came into this world. They have pioneered many things, such as inventing science and technology and exploring space. These achievements have propelled human race to new heights, giving them the ability to understand the universe and improve their life on Earth. One of their most groundbreaking creations is Artificial Intelligence (AI), which is even more powerful and efficient than its creators in certain aspects. Despite these remarkable achievements, the future survival of human race appears to be fraught with challenges. One significant limitation lies in their inability to venture beyond the boundaries of their solar system. I’ll try to explore the reasons for this limitation in the following paragraphs.

I think humans have almost reached the peak of their evolution. Over millennia, they have developed the highest levels of intelligence and mental capabilities. These advancements have enabled them to create art, invent complex mathematics, machinery, and uncover the mysteries of science. However, with this intellectual growth, their physical bodies have also undergone significant changes. It is certain that the modern humans are no longer as robust as our ancestors. The human body has become increasingly fragile, making it less suitable for sustaining in a futuristic environment (much of this is caused by them) that demands extraordinary endurance and adaptability.

Traveling across the universe has become a monumental challenge for humans. To reach the distant stars and galaxies, humans would need to achieve speeds close to the speed of light. Travelling at such speeds, however, seem implausible for their biology. Even if they are able to build an engine powerful enough to propel a spacecraft to the speed of light, the human body cannot endure the extreme conditions associated with such travel. For instance, current technologies like jet planes and rockets has already pushed the limits of human tolerance. As speed increases, so does the G-force experienced by the body. At near-light speeds, these forces would become catastrophic. Human tissues may be torn apart, and cellular structures may collapse under the immense gravitational forces. This physical limitation alone makes it impossible for humans to travel to far-off galaxies. Additionally, sensory organs like the eyes and ears, which are essential for perception and navigation, would fail to function properly at hyper-speed, further compounding the challenges.

Even with theoretical advancements like warp engines, the problems faced by humans would not go. Warp engines, designed to manipulate space-time and achieve faster-than-light travel, would introduce their own set of challenges. One of the most significant issues is time dilation, a phenomenon predicted by Einstein. At high speeds, time for the travelers would slow down relative to observers on Earth. While this might sound advantageous, it would have devastating effects on the delicate human cells. Prolonged exposure to such conditions may cause irreversible damage to the brain and other vital organs. This biological limitation renders interstellar travel an impractical dream for humans.

Natural history is also not encouraging. We are aware that nature has produced countless life forms in the past that have flourished and then faded into extinction. Dinosaurs and other prehistoric creatures were once dominating the world but eventually succumbed to environmental changes, catastrophic events, or competition. Similarly, humanity may face extinction in the distant future. Factors such as environmental degradation, nuclear warfare, pandemics, or the impact of a celestial body could threaten human survival. While humans possess the intelligence to foresee and mitigate such threats, their biological limitations becomes an insurmountable barrier to their eternal survival.

This raises a profound question: If humans were to go extinct, who or what would rule the planet? Animals, while resilient, are also constrained by the fragility of biological materials. In contrast, robots equipped with Artificial Intelligence present a viable alternative. Unlike humans, these machines would not be limited by the vulnerabilities of a biological body. Robots can be designed to withstand extreme conditions, operate indefinitely without fatigue, and process information at the speeds which is impossible for human capabilities. With AI advancements, these machines would not only equal but surpass human intelligence, making them the ideal successors. They could undertake tasks that humans could never perform, such as exploring the harshest regions of space or enduring conditions that would destroy organic life.

The only conceivable way for humans to secure their place in the future would be to transcend their biological limitations. This could involve transferring their consciousness into machines, effectively merging human intelligence with the durability and efficiency of robots. Such a development would mark a new era in human evolution, ensuring their legacy to stay forever. Until this becomes a reality, humanity's chances of survival on this planet and beyond remains uncertain. The possibility of extinction serves as a stark reminder of the challenges that lie ahead for us. It emphasizes the need for innovation and adaptability in the face of an unpredictable future.
