What happens when the software you use starts acting independently? Harry Glorikian calls this the invisible interface, and in this episode he unpacks the implications of unseen agency and autonomy in the future workforce. Topics: the personal interface layer;  the memory war;  who owns the context that makes a personal interface valuable; proofseconds;  the four trust signals that determine whether human users are willing to delegate to machines; how occupational dimensionality determines whether an employer will automate an entire job or just parts of it.
