Reply to comment by verasev in Mitochondrial DNA Is Working Its Way Into the Human Genome by molrose96

Ya, you're right about surviving. This next part is my personal view of evolution. I have begun to think that biological evolution is only the first step of evolution. Social bonds is the 2nd step in that knowledge gained through lifetimes can be passed down through generations through culture rather than just hard-coding behaviors into our DNA. To get from step 1 to step 2 takes the longest but each step is exponentially faster to progress. Step 3 is technology that emerges as a natural consequence of culture and generational knowledge. Step 4??? Maybe it's AI? Step 5??? Maybe it's revisiting step 1 and editing our own genes. Like I said, I expect each step to be faster than the previous.

I imagine the line between mechanical and biological will also blur and you'll have organic robots. So it could be both AI and gene editing. I've contributed to culture through raising a step-son but I'm a dead-end biological reproduction-wise. And I'm here on the internet, scribbling in the margins of human culture's great big electronic record book. Who knows what parts of me will persist? Probably nothing significant.

I've thought along similar lines. There are multiple levels of "intelligence", each building upon the last and characterized by a new, faster, and more efficient way to process and store information about how best to live.

    1. Dumb matter
    1. Life - stores information about how best to live as DNA; updates it via evolution; passes it down via reproduction
    • 2a. Life with isolated brains - stores information about how best to live as synaptic weights; updates it via thinking; no ability for thoughts to be passed down
    1. Brain that can speak - stores information about how best to live via often-retold stories; updates it via making up new stories or modifying existing ones; knowledge is passed down by retelling stories to children - the genesis of family
    1. Brain that can write - stores information about how best to live as persistent symbols applied to physical objects; updates it via publishing new works or modifying existing ones; knowledge is passed down by duplicating these works - the genesis of society
    • 4a. Brain that can write very efficiently - printing press, radio, telephone, television, the computer, the internet - we are here
    1. ??? - anything that makes updating memory faster, particularly if it allows also updating lower levels (e.g. humans currently find it much easier to update their memories than to update their DNA)
