No reason to be nervous, all 737 MAX are grounded worldwide. I doubt they will be certified to fly without adding the triple redundant AOA sensors the A320neo has and that should have been included from the very beginning. If the FAA certified the 737 MAX without a mandatory upgrade (doubtful, given the glare of publicity), then yes, I'd be worried.
