Boeing's response- blaming the pilots, not their shit MCAS software and AoA sensors, is the problem.
Blaming the victim minimizes the criminal act.
Even if it was the crew's error, no (undocumented) system should be designed to rely on "a memory item" to stop a fatal dive.

Blaming the victim minimizes the criminal act.Well, many people have wondered why they didn't execute the "uncontrolled stabilizer trim" checklist in both flights. It's not "blaming", it's wondering.Even if it was the crew's error, no (undocumented) system should be designed to rely on "a memory item" to stop a fatal dive.I think that thou dost not understand the point of an emergency checklist.

Today, a detail this small could be the root cause but here we are blaming the pilots.
Blame the humans when the automation system intended to save them, kills them.
I think you are having a hard time understanding why planes crash. There is not one reason. There is never "one" reason.
@floobydust : knowing what you know, do you think you would have turned off those two switches or not?
Well, bombshell, pilots followed emergency procedures that were laid out by Boeing. This Boeing fkup could be even bigger than expected, and yet many will still blame the pilots

It can't do anything if you cut power to the jackscrew motor with the stab trim cutout switches.
This is interesting as when the power failed on this Russian plane the pilots used a glass of water in order to keep the right attitude. I guess they may have had more time to sort things but they were also trained in what to do if the electronic system did fail perhaps these days there is not so much training and it certainly looks like the manufacturers make no allowances for total failure of the systems. It begins to look like they might even be trying to lock the pilots out of the systems now.

I don't think so.
..Many (well, a few, or some) pilots in previous 737 MAX flights have saved the day by doing just that. Why? How did they know? Because after the lion air 610 crash Boeing put out a safety technical bulletin explaining just that. We're going in circles in this thread...
I do not want to fly in a plane where the pilots have to manipulate those switches in order to save my day..

This is a cool story, but some of those details seem very dubious. For example, a glass of water cannot be used as a substitute attitude indicator*** for the same reason your ear cannot be used for such: it can make no distinction between the acceleration of gravity and other sources of acceleration. Hence, you can easily "death spiral" an aircraft all the while with the water level. In any case, the video makes it clear that they dropped below the ceiling in order to see the ground; at that point they would not really need an AI anyway.
I also notice the wikipedia page for the incident mentions no glass of water.
I see how the loss of electricity caused them to lose their nav capabilities. I wonder, though, why they didn't still have use of primary instruments. Airspeed indicator, altimeter and vertical speed indicator do not need power at all. AI and DG are usually vacuum driven, but I can imagine them being electric in an airliner. But it would be a poor design choice indeed for that electric system not to be backed up by something non-electric. Turn coordinator usually is electric, so that would go.
Of course, on a modern airliner these sensors are all integrated onto screens, but if you look around you can usually find some or all of them duplicated somewhere on an old steam gauge.
