The 737 MAX with the MCAS fix is as secure as any 737 out there. Perhaps even more so due to having new engines, all of them being new air frames and because to my understanding in the review of the software they found and fixed another issue which always has been present. One can certainly argue, that Boeing should have invested into a true 737 successor a long time ago instead of updating the old design, especially with all the restrictions of keeping the same type rating. The problem is, this hasn't happened. Assuming air travel bounces back to pre-Covid levels, there is a huge demand for 737-class airplanes. Like thousands. Creating a replacement (which Boeing really should start like yesterday) will take about 10 years, you don't want to rush that, if you don't want to create an even larger security problem (just look to the 787 for initial problems and ongoing reports about manufacturing issues). So for the next 10 years, the option is either to fly the 737 MAX, fly much less or with aging 737 air frames from the pre-MAX times.
