By Michael Altfield, on December 9th, 2025

I’m super happy that Techlore invited me on their YouTube channel to talk security and privacy 😀

Henry was mostly interested in my work with BusKill (an open-source dead man switch), but our conversation ran a gamut of issues regarding security and privacy — including
