Fear. Right now we're on the edge of facing fear or succumbing to it

The Dark Forest theory is a great answer to this paradox. Anyone more advanced has a rational choice to exterminate all competition. We haven’t found any other advanced life because it hasn’t shown up and killed us yet.

Hard to determine with what we know. We haven't met any other intelligent species which suggests we've passed the filter. Yet, making that conclusion before knowing there are no others to meet is too presumptuous. But, if I were to guess, I'd think the filter is adaptability.

We're superior to animals for being able to use tools, live in radically different climates, and shape every spot on earth into a livable climate. Even on Mars, the moon, and space. How else would a species venture through space if they can't adapt?

That might be too general a concept for the question though.

I don't think life is rare, nor photosynthesis, but complex life might be. A planet needs to be really thriving with life for it to be worth it to go down the path to something like animals

But I think the bigger filter is much stranger.

Humans are a hive-like species. We're not just social - we're insanely interdependent, we don't function on our own and yet we've ended up in this place where we (often) try to individually succeed, even at the cost to our community

We're greedy enough to want the stars, yet interdependent enough we could only swarm over them in endless numbers

There's many problems with the fermi "paradox", but personally I think one of the largest is assuming all species would spread like a cancer blotting out the stars

A more individualistic and long lived species might instead be careful explorers, taking what they need and leaving little sign of their passage. A more communal species might be careful and control themselves to not destroy pointlessly. They might also feel no desire to contact other species

We're just the right mix to want everything a star could give, and to want to find others at great energy cost

Exponential functions. Seriously. You meet crisis after crisis, each having a risk of ending civilization, but that risk never goes away. It keeps multiplying and multiplying, until you realize the risk curve is approaching a vertical line

I'm starting to wonder if its LLMs. An AGI is something we would be incredibly cautious around and is really no more likely to be psychopathic than any other living thing, the vast majority of which are not. LLMs on the other hand are pushed into every role techbros can shove them into while having less understanding of what they do than a housefly, the potential for damage is immense if someone decides to put one in charge of something important like infastructure or weaponry.

Your answer doesn't make sense.

"Photosynthesis" is a positive development for life. The great filter must be a negative development: it's a filter or a barrier that keeps life from achieving long term extra terrestrial survival.

So "climate change" would be an answer. Or "fuel depletion" (to which photosynthesis may be a solution). But the filter is the mechanism by which life forms are prevented from progressing.

I think most lifeforms will have more pressing matters than wasting large amounts of time an energy blasting signals in to space for no reason, or listening to the sky.

Maybe those civilizations that waste more energy chasing aliens die off sooner due to wasting resources on sci-fi bullshit and ignoring their real problems at home.
