[$] Looking back at 2023

Yet another year has come to an end. Much to our dismay, 2023 did not, in
fact, happen exactly as we predicted back in

process of looking at the predictions that we made and mocking each in
turn, before getting into what was missed altogether. A lot happened in
2023, not all of which was predictable.
