You seem to believe that computer software and hardware has no error detection and correction built into it. This is definitely not true. The reproducibility of computer-derived knowledge is what makes it something we can trust. Especially if it's being reproduced on disparate hardware and disparate software. Mathematics is possibly the only thing in the entire world that can _not_ be described as a religion.
