I'd be curious to hear from anyone who's a pilot (I know there are a few of them here).

What are the interactions between an automated system and the pilot?

Specifically, can a plane quickly switch from flyable to out of control?

There's a huge number of unknowns here, but I thought most pilot assistance systems were designed to be disengaged if needed.

These forums have several threads about the recent crashes and grounding with some experienced pilots discussing. https://www.airliners.net/forum/viewforum.php?f=3

Here's a pilot describing the new MCAS system on the 737 Max, and what a pilot would feel:
