The theorem generalizes the undecidability of the halting problem. It has far-reaching implications on the feasibility of static analysis of programs. It implies that it is impossible, for example, to implement a tool that checks whether any given program is correct, or even executes without error (it is possible to implement a tool that always overestimates or always underestimates e.g. the correctness of a program, so in practice one has to decide what is less of a problem).
