I have seen a CNN expert discussion about that incident. In 2005 the pilots were able to get control of the plane by going manual. But that may not always be possible if the pilots are not sufficiently trained to deal with sudden, catastrophic, malfunctions of the automatic pilot.

Then there was the Boeing warning about a fuselage structural problem at the satellite antenna that could lead to sudden decompression, 5 months ago:

What are this boards experts opinions on this information?

Autopilot failure? There should be warning lights to indicate this. Corrective action can be made by the pilots.
Structural failure? Can lead to decompression and pilots can correct for that.
Too much structural failure and aircraft can get out of control beyond pilots' capabilities.
