Well that’s kind of what happened. The primary flight computers all failed, to the plane fell back to “direct law”, which means pilot input is directly transmitted to control systems without a computer attempting to interpret intent or protect against pilot error. As a consequence a lot of the more advanced functions became disabled because they rely on the primary flight computer to indicate when it’s safe for them to operate. Presumably because accidental operation of those features in flight is extremely dangerous.
