My understanding is that the Airbus equivalent (they don't really have the same thing) uses 3 pitot tubes/angle of attack sensors, not 2. More importantly, Airbus pilots know about the system, while Boeing only told airliners about MCAS after the Lion Air crash.

I'm not a pilot and I don't know that much about planes, but I've read/watched enough about crashes to know that these sensors fail way too often. To rely on only one already sounds like a bad idea, but it's irresponsible not to tell pilots and train them on how to deal with the new "feature".
