One of the most serious side effects is a toxicity in the eye (generally with chronic use).[11] People taking 400 mg of hydroxychloroquine or less per day generally have a negligible risk of macular toxicity, whereas the risk begins to go up when a person takes the medication over 5 years or has a cumulative dose of more than 1000 grams. The daily safe maximum dose for eye toxicity can be computed from one's height and weight using this calculator. Cumulative doses can also be calculated from this calculator. Macular toxicity is related to the total cumulative dose rather than the daily dose. Regular eye screening, even in the absence of visual symptoms, is recommended to begin when either of these risk factors occurs.[12]
Any competent engineer would raise moral and ethical questions when working on software that is "mission ciritical". Causing a passenger plane to continually go into a nose dive because of data coming from a single sensor is absolutely ludicrous. Just because the software was horribly designed, doesn't mean it isn't a software issue.
