    I have a calculator that is correct 80% of the time. But don't worry, every time I use it, I check the results myself.

    @MartinEscardo if your calculator burns half of the planet to operate you could get your correctness to 90%. Would that help?

      @MartinEscardo my reports are correct 85% of the time but that's ok, my boss is happy to double check them before sending them to our customers!

        @MartinEscardo hello sir

        i am not a mathematician, but the results look correct to me?

        in fact i feel like a 10x mathematician now, i can calculate and calculate all the time

            @MartinEscardo Reminds me the early Pentium FDIV bug in the mid 90s: Recommended mitigation measures were to verify the computing results using an older but reliable 486.

              @MartinEscardo just give it autonomy and chain it to another autonomous calculator that verifies the results with an 80% accuracy.

                    @MartinEscardo just launch 100 calculators and pick the most common result, it should be fine

                        @MartinEscardo Can you somehow make the calculator physically bigger? Bigger isn't better but it is inevitable and innovation.

                            @fbulow @MartinEscardo

                            If the calculator is only correct 80% of the time, one could use two calculators, so that the correct result appears at least on one of the displays ~96% of the time.

                            As a side effect it would double the size.

                                    @MartinEscardo These things get better and better. Might be correct 90% of the time by 2027!

                                        @MartinEscardo I was taught to do at least an order-of-magnitude mental sanity check every time I used a calculator - there's always scope for pressing the wrong button.

                                        @TimWardCam @MartinEscardo There is always scope for errors.

                                        I love these discussions that assume humans are the golden benchmark that never makes mistakes or errors.

                                        As you correctly were taught, check your work if at all possible.

                                        And all the clever rules that apply to how to deal with outputs from algorithms apply to human output too. Potentially with modification, because humans can lie maliciously. And with that observation, let's close that argument with a round of “they eat the dogs”

                                          @MartinEscardo Funny enough, for some calculations a real calculator and the iOS calculator disagree. The physical calculator does all operations left to right, where the iPhone calculator does all operations by order of operations resulting in different sums in the end.

                                          How many people knew that, and how many have trusted the calculator all these years?
