You cannot get rid of the enviroment, and the best thing you can do is be explicit in what you rely on. For example, formally verified operating systems often rely on hardware correctness, even though the errata sheets for modern CPUs are hundreds of pages long.
Presumably it is much harder to sell now. If you didn’t want it, why buy it in the first place?
For additional fun: Swiss German doesn't use ß at all, so there is no difference between "in Maßen genießen" (to enjoy in moderation) and "in Massen genießen" (to enjoy in large amounts).
Take the Halting program for example: For a program p which halts, you can determine whether it will halt in finite time (because by definition it halts). However, there is no semidecidable algorithm for "this program runs infinitely long".
Thanks!
