Exactly my point -- we've just seen 346 people killed by (presumably) an anti-stall system -- when it's been a decade since we've had the problem this system is meant to prevent.
If the 737 MAX anti-stall system has a flaw of course it should be fixed. That's hardly an argument against anti-stall systems in general. The accidents prevented by anti-stall systems don't make the news.
Yeah, it is tough to assess without knowing the likeliness of a stall, and the likeliness a stall causes a crash. Otherwise, we run into the problem of having such a small sample size.
