If by deficiencies you mean 'clairvoyance' especially in terms of the lion Air pilots then many would be in complete agreement with you.
I will reserve judgement until the final reports are out, but it appears he isn't wrong. Why the Lion air crew didn't jump on the "RUNAWAY STABILIZER' NNC is an issue. On the 737, it's the only proper checklist to address any uncommanded and/or inappropriate movement of the stabilizer. If they didn't know that, it's a clear deficiency in their training.
The wildcard with ET in my mind is the normal stab trim system. Boeing states it will stop, and reverse the MCAS trim commands. If it was working as advertised, then the crew wasn't flying the airplane, it was flying them. Thats another training or experience issue.
But again, the full CVR transcripts, and final reports should clear a bunch of this up for everyone.
They were dealing with issues from the moment they took off. With multiple issues to deal with runaway stabiliser was down on the list. Pilot overload.
Once the airplane was under control, the uncommanded stabilizer movement was far and away the biggest threat for that crew. Had it been dealt with properly, and in a timely fashion, we wouldn't be having the conversation we are.
Multiple failures/issues with spurious warnings is a challenge, but is not an insurmountable problem.
