For sure, the issue is bad, should be resolved, and should have never been certified in the first place. But given the amount of attention the problem has received from all stakeholders, I think any further worries about MCAS from the flying public are misguided. The least likely thing to kill you is usually the issue that everyone is thinking about and is actively working to mitigate. Mechanical issues are especially terrifying because they remove any sense of human agency, but the good thing is that humans are good at fixing them. Human fallibility is a much tougher problem to solve and is still by far the most common reason airplanes crash.
