I don't really understand. If one accelerometer fails for years and nothing is reported it is a big failure on the design team, probably with criminal responsibility. Depending on GPS for main navigation is also very bad idea. In the near future with the cost of today one fiber optic gyro and accelerometer you will be able to buy ten. Software will improve and redundancy like it has done tremendously in the past making airplanes the safest of transports precisely because it does not depend so much on fallible humans that get tired and need to rest,pee and other biological necessities, have ego(that blinds their judgments) or get in love with the air hostess,get bored(some flying could bore you to tears) have problems of vision or hearing with age, get distracted(and lose situational awareness) or ill or intoxicated by food. It is easy to forget that death was what we had when humans were in charge. We are talking about thousands of times more dangerous than today. So the title is yellow sensationalistic garbage. The only reason humans have not been completely replaced is because people naturally trust other people more than machines, landing on side winds automatically requires engineers taking responsibility for it(and nobody had sone so, so far), and someone needs to be in charge in the plane at all time(for example what to do if a person have an stroke).
