And equally importantly, other planes don't crash nearly as much. Boeing managed to make a new plane that's much more deadly than existing planes on the market. It doesn't even matter so much why it's more deadly, just that it is. Placing blame on pilots misses the point, when those same pilots would not have crashed in those same conditions in a different plane.
Well it can matter if it turns out the issue wasn’t engineering so much as clearly communicating that it’s a different aircraft so the pilots can be trained correctly.
It's still unacceptably dangerous even if this difference is communicated. To be safe, at a very minimum you would need triply redundant AoA sensors, an MCAS engaged notification, and an MCAS cutoff switch.
There is an MCAS cutoff switch and the side effects of MCAS runaway are visible on the trim wheel. This was a non-issue for the pilots that were correctly trained.
The whole point was to reuse the 737 typing. Boeing messed up. (Other parties messed up too, but Boeing started this.)
This is basic Human Factors 101. Designing something where some percentage (even a small percentage, and especially when tragic consequences are involved) of properly trained people will be confused by the design means the design is at fault, not the people.
