Tony Hoare, winner of the Association for Computing Machinery's A.M. Turing Award, discusses the origin of his model of "Communicating Sequential Processes" and the central importance of keeping processes from directly accessing the state information of other processes. This clip taken from an interview conducted with Hoare by Cliff Jones for the ACM on November 24. 2015. Video of the full interview is available as part of Hoare’s ACM profile at https://amturing.acm.org/award_winners/hoare_4622167.cfm.
