Obviously not. There is a difference between blaming the pilots - I am not, and saying the plane was "unrecoverable" the system was "unstoppable".
Luckily if flying in the US the chance of the AoA being faulty in the first place would be a less I would argue than flying for lionair. My co-pilot might be quick to help. I might be quicker to get off automation and manually fly / trim.
Some of the self reports from the US specifically credit co-pilot assistance in averting a problem. See this one during takeoff - worst time to be heading towards ground at 1,500 FPM!
Within two to three seconds the aircraft pitched nose down bringing the VSI to approximately 1,200 to 1,500 FPM. I called "descending" just prior to the GPWS sounding "don't sink, don't sink."
Other side:
"PM's (co-pilot) callout on "descending" was particularly quick and welcome as I was just coming back to my display after looking away. System and procedures coupled with CRM (Resource Management) trapped and mitigated issue.
Synopsis
B737MAX Captain reported an autopilot anomaly in which led to an undesired brief nose down situation."
This was a full GPWS don't sink alert situation - very cleanly handled - the co-pilot BEAT the automated alert, the recovery was good. Should pilots have to deal with this? No. Did chain of safety work here? Yes - though closer to edge than one would like.
My own impression - US pilots much quicker to get off the automation / don't trust it as much / have more comfort or experience hand flying statistically maybe.
