It wasn't necessary to know MCAS existed - the procedure for runaway trim is in the manual and is the correct response to MCAS failure as MCAS failure exhibits itself as runaway trim.

Turning off the stab trim with the cutoff switches is part of the memory procedure to deal with runaway trim, and no superhuman abilities are required. Just remembering to do it.

Not at all. I just take issue with the claim that pilots had no role in the accidents, and take issue with the bad design of the MCAS software being a cost saving measure.
Note that the fix is redesigning the MCAS software.
I did read the article, and that isn't what he said. Furthermore, Captain Sullenberger is an Airbus pilot and hasn't flown 737s in a long time and is not rated on the 737NG.
I don't know what runaway trim procedures are on Airbus airplanes.
If an aircraft starts pitching down, and it wasn't commanded by the pilot, and resetting the trim (temporarily) fixes the problem, the issue is almost certainly with the trim. If it is MCAS and a malfunctioning sensor or a failing motor that occasionally kicks on and drives the trim to its limits, the pilot response should be the same. This is what I hear Walter saying, and it makes sense. MCAS just makes it more probable to manifest.
Hence, they might not have thought it was a trim runaway.
That’s beside the point. In the story they discuss how airplanes are not intended to require this level of superhuman ability to stay airborne.
You are avoiding that this was a combination of an engineering flaw (reading from a single AOA sensor guiding MCAS, when in reality it should have been redundant) and a regulatory flaw (the role of MCAS was increased despite it being initially regulated as a much milder intervention).
