In 2019, I gave a keynote presentation at the Alternative Education Resource Organization’s (AERO) annual conference in Portland, Oregon. Founded in 1989 by Jerry Mintz, AERO has long supported entrepreneurial educators in launching new schools and spaces, with a particular focus on learner‑centered educational models. It was about a month after my previous book Unschooled was published, and I was talking about the gathering interest in unconventional education. Homeschooling numbers were gradually rising, and more microschools and microschooling networks were surfacing. I predicted that these trends would continue, but I said they would remain largely on the edge— as alternative education had for decades.
