Recently, I enrolled in two multi-day training workshops in the United Kingdom with the pretense of gathering ethnographic data about emergent cultures of practice surrounding new technologies. The first was an ethical hacking workshop in Manchester–where we learned how to “ethically” use malware to examine, test, and ultimately penetrate and control computer servers. The second was a class to acquire a certificate to be able to conduct commercial drone flights. These experiences revealed interesting insights into the process of professionalisation as well as contemporary ethnographic methodologies. I will briefly theorise the process of professionalisation, how this happens, why it is interesting, and why training-as-ethnography is an important place to participate in this process.
