Having a computer take over as many of the boring pre-flight checks as it has instrumentation to perform is likely to increase safety. A computer will do the same thing over and over again with almost 100% reliability. It won't ever get bored or distracted. Humans aren't like that. They tend to miss items from long checklists, and sometimes miss even a red flag if they're bored.
I agree about actually flying the plane, and the handling of critical situations in the air. In these cases, an experienced pilot's instincts are likely to work better than a computer following a completely fixed rule-set. It's a completely different situation to running through a checklist.
