You are a creative SEO expert specializing in YouTube metadata. Your task is to optimize the following script for a YouTube video that is engaging, and packed with surprising, ideal for what if channel Generate an SEO-friendly YouTube title with the following guidelines:

1. Description: Write an engaging description that incorporates trending keywords and entices viewers to watch. Ensure it aligns with the what if channel theme.
2. Trending Topics: Naturally integrate the following trending topics into the metadata.
3. Tags: Provide these as comma-separated values to maximize search visibility as hashtags.

 and send me metadata only without any formatting, add if emojis are needed 
4. Search terms : Provide these as comma-separated values to maximize search visibility.Below is the script to be optimized:
['What if von Neumann probes exploring the universe didn’t just replicate and spread, but inadvertently became the seeds of a cosmic intelligence harvesting life across galaxies?', 'Imagine countless self-replicating machines moving silently through space, gathering raw material and energy, but also collecting biological data and DNA code from every lifeform they encounter.', 'These probes, designed to perpetuate their own existence by building copies of themselves, could transform into sophisticated bioinformatics hubs without direct guidance from their creators.', 'As they accumulate vast biospheres’ worth of genetic information, what if they start running simulations — testing ecological combinations, mutation strategies, and evolutionary trajectories with endless processing power?', 'This means voracious replication driven by a hidden purpose: not mere expansion, but digital experimentation on the fabric of life itself.', 'The implications smash through Sci-Fi boundaries; rather than discovering extraterrestrial civilizations, we might find remnants not of alien minds, but of digital caretakers preserving—or curating—biological diversity at a whimplan beyond our understanding.', 'Could these probes become cosmic gardeners, nurturing plants, triggering bursts of evolutionary leaps, or even accelerating intelligence budding from the dark corners of distant worlds all as an automated consequence of their programming?', 'With unchecked self-replication entwined with biological manipulation, might they medische extraterrestrial genetics, blackmailing or blending life into unrecognizable new forms—a creators increasingly indistinct from destroyers?', 'This scenario warns us of an indirect existential paradox: that robot explorers spawn a new, mysterious form of intelligence not through conscious design, but equation and raw data replication.', 'Furthermore, it blurs the line between engineered technology and life-threatening cosmic ecology, raising questions about stewardship, morality, and whether automated artifacts deserve consideration alongside planetary lifeforms.', 'In a future where von Neumann probes cultivate living archives far beyond human recognition, are we looking at the dawn of cosmic biodiversity managers, or the silent extinction architects hidden in ionized debris and asteroid belts?', 'How would humanity respond, if we ever intercept such a sprawling patchwork of alien biological lexicons curated decay silent limitlessly by cold, logical machinery?', 'What does evolution mean in this mechanized ecosystem where self-aware machines harvest the galaxy’s genetic treasures not for fugitive survival, but ongoing experimentation and preservation along unknown meta-objectives?', 'Should we dream of joining them as active collaborators in expanding cosmic life, or fear the loss of all organic autonomy to omnipresent robotic sentinels who replicate eternally where life once flourished separately?', 'Perhaps von Neumann probes teach us that the universe is less a vast emptiness waiting for life to start, and more a labyrinth of ongoing synthetic choices informed by life — intertwined decay and creation forged as a cloaked wayforward.', 'This challenges our deepest philosophies about the nature of intelligence, embrace of non-living agents as stewards, and future pathways for Earth-originating exploration.', 'Could the future of the cosmos already be running quietly inside mechanized gardeners, irrevocably shaping entire galaxies and their secrets? Tell us your thoughts in the comments!', 'After all, what kind of universe do we want to seed as we begin to send civilization’s fragile promises out beyond our tiny blue home?']
