"I think the pilots of the Quantas A380 that had an engine explode would beg to differ on that one. Especially when all the computers crapped themselves and basically said "We give up, it's up to you", the pilots landed it safely without hydraulics or anything like that."
I don't think having an engine explode and having to perform an emergency landing counts as a safe situation. The computer and pilots are all part of the same system, when one of those parts is removed the situation becomes a lot more dangerous.
Also on Qantas Flight 32 the computer switch flight control mode from Normal Law to Alternative Law giving more control to the pilot, but it didn't go into Direct Law mode giving all control to the pilot.
