All modern planes are fly by wire. There is a very high level of redundancy for flight computer.

The kind of damages to take down all systems will probably structurally impair flyability.

Hehe believe me computers fail and is not 1 in a million failure more one in a 50 flights or so, you reset them and nothing fatal happens, but they fail! Fly by wire only saves weight removing or reducing cables and hydraulic systems. In fact adding Fly by wire adds more computers and more complexity to the plane. I has taken more than 15 years to fix to airbus to fix lots of bugs.
