This used to be a big reason why we used computers --- to help eliminate the probability of error.
But apparently, not so much any more.
Right, it was the perfect match: Humans for fuzzy touchy feely stuff, computers for hard edged correct calculations. How have we managed to screw this up so badly?
Digital computers were named after the humans whose jobs they automated out of existence.
They were invented to reduce cost of computation, not to eliminate the probability of error per se. Ask a Windows 11 user, they'll tell you computers still make errors.
