The awesome folks at Software GR in Grand Rapids, Michigan invited me to come and give a talk about ... anything I wanted! It was quite an honor to be asked and I delivered a talk I've been wanting to give for a long time. I decided not to include the speaker notes this time because they're still a work in progress. Consider this a first step towards a more well developed talk that I will give at the end of March. You can find the bibliography/works cited here.
