Well a lot of them didn't fall out of the sky and were used like millions of times, and the reason a few of them did was ostensibly fixed so now the chances of them falling out of the sky is even less than when most of them already weren't.
the need for MCAS in the first place is a major design flaw and results in additional failure modes that other aircraft do not have. the "fix" was to prioritize human inputs over MCAS, making these planes more vulnerable to human error. still worth avoiding IMHO.
