Over on MO (in the comments here) Stefan Wendt kindly reminds me of an old $n$Lab entry I once started on B1-homotopy theory. Have added a reference and hope to be adding more.
Following the reference to Ayoub there, I see his 2014 ICM talk is available. It begins
The (co)homological invariants associated to an algebraic variety fall into two classes:
(a) the algebro-geometric invariants such as higher Chow groups (measuring the complexity of algebraic cycles inside the variety) and Quillen K-theory groups (measuring the complexity of vector bundles over the variety);
(b) the class of transcendental invariants such as Betti cohomology (with its mixed Hodge structure) and l-adic cohomology (with its Galois representation).
The distinction between these two classes is extreme.
Is this a form of fracturing?
