The Fermi Paradox—where are the aliens?—can be explained by the "Great Filter" theory. Astrophysicist Alex Filippenko believes this filter is likely in our future, meaning civilizations like ours often destroy themselves before colonizing the galaxy.

Coined in 1965, the "intelligence explosion" describes a runaway feedback loop. An AI capable of conducting AI research could use its intelligence to improve itself. This newly enhanced intelligence would make it even better at AI research, leading to exponential, uncontrollable growth in capability. This "fast takeoff" could leave humanity far behind in a very short period.
Elon Musk's take on the simulation hypothesis includes a 'Darwinian' twist. Just as humans discard boring simulations, any creators of our reality would do the same. Therefore, the simulations most likely to continue are the most interesting ones, making 'interesting' outcomes the most probable.
Humans branched off from gorillas evolutionarily and now, due to superior intelligence, control their fate entirely. This analogy illustrates that intelligence is the single most important factor for controlling the planet. Creating something more intelligent than us puts humanity in the precarious position of the gorillas, risking our own extinction.
The Fermi Paradox asks why we see no evidence of alien life. A compelling answer is that any civilization with technology for interstellar travel would have already developed superior virtual realities. Exploring infinite digital worlds is safer, cheaper, and more efficient than physical travel, making it the logical path for advanced species.
There's a stark contrast in AGI timeline predictions. Newcomers and enthusiasts often predict AGI within months or a few years. However, the field's most influential figures, like Ilya Sutskever and Andrej Karpathy, are now signaling that true AGI is likely decades away, suggesting the current paradigm has limitations.
The force of gravity is precisely tuned for life to exist. If it were slightly weaker, stars wouldn't ignite; slightly stronger, the universe would have collapsed. This 'Goldilocks' condition is so improbable that some scientists argue it suggests our universe is just one of many, most of which are sterile.
The discourse around AGI is caught in a paradox. Either it is already emerging, in which case it's less a cataclysmic event and more an incremental software improvement, or it remains a perpetually receding future goal. This captures the tension between the hype of superhuman intelligence and the reality of software development.
The reason we don't see aliens (the Fermi Paradox) is not because they are distant, but because our spacetime interface is designed to filter out the overwhelming reality of other conscious agents. The "headset" hides most of reality to make it manageable, meaning the search for physical extraterrestrial life is fundamentally limited.
A novel answer to the Fermi Paradox (why we haven't met aliens) is that any sufficiently advanced civilization inevitably finds creating infinite, engaging virtual worlds more compelling and energy-efficient than interstellar travel. AI is the technology that will lead humanity down this same path of virtual exploration.
The search for extraterrestrial life focuses on "chemical disequilibrium." The simultaneous presence of oxygen and methane in an exoplanet's atmosphere would be a strong indicator of life, as they naturally destroy each other, implying a constant biological source is replenishing them.
