Well, I can confirm that I've seen the machines in action. At the time that they were being developed, at the concept stage, I suggested that there were much more effective priorities and, in fact, that taking the step of responding to people who are living in poverty.... It's important to note that these machines were installed in what are referred to as low-barrier housing developments. From prior research, one of the things that was most urgently needed among people who were socially estranged, including those in low-barrier housing, was the opportunity to be engaged in meaningful relationships and on a path to social reintegration, which, by the way, is something that harm reduction interventions are capable of initiating.
I thought it was exactly the wrong type of message to take, as we were in the first year of a declared public health emergency, in that rather than engaging alienated people interpersonally, we would instead be pouring our energies and attentions into an interface that involved a machine, but my view was fairly forcefully outvoted by people in positions of authority.
