"Crappy sensor failure, crappy software failure, crappy aerodynamic failure" would be the chain of events, because the pilots did everything right.
The pilots in Ethiopian and all the passengers paid with their lives for a whole world to learn that.
The world knows because one pilot tried to partially reconstruct the conditions on his own in an older simulator, as there were effectively almost no new simulators because the Boeing's selling point was that the new model of the plane is same as an old one model, just to avoid the recertification and pilot retraining. So the said pilot did the test for youtube, showed that what the pilots probably did matched the emergency procedure, and that exactly that following the procedure most probably results in the crash, but had to remove the video once his employer became aware of what he did.
I've posted the link to that original source then, but HN moderators marked it then as a "dupe":
