I'm not in aeronautics obviously and I overstated the case, but my understanding is that the MAX series have different flight characteristics (behaves differently) due to bigger engines which also were moved forward both of which resulted in altering the aerodynamics and flight characteristics --making it different to non MAX 737s... so far, so good. They fly different and you have to treat them differently. But in order to make the pre MAX 737 pilots pre-crosstrained for the new MAXes they installed MCAS systems that made the controls feel like they would respond in a pre MAX 737. In other words computerized compensation. But due to the new flight characteristics you could not exactly fly it like a ore MAX 737 and so if you did bad things could happen if you were not being attentive.
