In the future, the 737 MAX will only permitted to resume passenger flights once the safety issue on the plane has been fixed.
The 737 MAX is still likely to become one of the most common planes in the world for many years to come, as it's predecessors in the 737 line have been. If you are planning to permanently refuse to fly on the 737 MAX because of this incident, you may wish to be aware of the safety records of... well, every other plane:
Older 737s, well, the predecessors of the 737 MAX have had their share of losses: https://en.wikipedia.org/wiki/List_of_accidents_and_incident... (Scroll up from there to see how many losses took place on even older models as well.)
And if you're thinking Airbus is going to be your savior here, there's a pretty solid list here too: https://en.wikipedia.org/wiki/List_of_accidents_and_incident... (Yes, it's much shorter, but the A320 series is a twenty year newer line.)
