    Limits and Risks of Digital Transformation by T. S. Akhromeeva, G. G. Malinetskiy, S. A. Posashkov

    Published 2020-07-01
    “…It is very likely that the tester of artificial intelligence systems will become one of the mass professions in the close future.We give examples to show that the "translation" from "continuous" to "discrete" language can lead to qualitatively different behavior of mathematical models. In a number of problems associated with a computational experiment this can be quite significant.Great risks arise when passing to the "fast world", approaching the "Lem's barrier". …”
