Classically, anabelian geometry asks to what

extent an arithmetic/geometric object is

determined by its topologically-flavored

invariants. Here "topology" primarily refers

to the etale topology. In this talk I'll discuss

a few results which arose while trying to

understand an "idealized" version of such

questions (I'll explain what I mean by this

during the talk), as well as some related

results which study the interplay between

certain "motivic data" and anabelian

geometry.
