The simple fact is that you have no idea of how safe or unsafe it is.
I'd hazard a guess that only the handful of people directly working on the testing and "fix" truly know that. The rest of us are basing our decision on safety on varying degrees of technical knowledge. I claim some inside/technical knowledge but way less than experts (as stated previously).
This 'I won't fly on it until after at least a couple of years' is an emotional response
Of course it is. Isn't that blindingly obvious from past comments! If you're an engineer and your shiny brand new car is recalled and fixed, you'd do the same thing. Try and understand it and judge if it's fixed and safe on the best knowledge you can obtain. No different to users of aircraft.
I apply the same logic to other a/c types that have had problems and certain airlines that have attracted the wrong sort of comments in the aerospace world.
