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)
