I will say that assuming the malfunction behind both accidents is the MCAS as it appears, the good news is that the fix is very doable.

Have it rely on both AOA sensors, with a comparator in order to identify bad data. And limit pitch trim to one 2.5 unit correction, so that it doesn’t continue to reset and drive further trim inputs.

And I believe that is the fix that was already being developed by Boeing, so hopefully it won’t take too long. And at that point there really shouldn’t be any reason to be concerned about the safety of the MAX series.
