Abstract:
The year 2019 sees the 50th anniversary of Tony Hoare's CACM paper, "An Axiomatic Basis for Computer Programming". In that paper, Hoare stated: "When the correctness of a program, its compiler, and the hardware of the computer have all been established with mathematical certainty, it will be possible to place great reliance on the results of the program, and predict their 
properties with a confidence limited only by the reliability of the electronics."
In this talk, I will review the 50-year history of this vision, describing the obstacles, the controversies, and progress milestones.  I will conclude with the description of both impressive progress and dramatic failures exhibited over the past few years.
