There really aren't two schools of thought there is only one.
Automate it.
Automation is not the complete answer, it's a system designed by fallible humans, this very thread is about the failed attempt to automate a system. There have been at least one accident cause by automation where the aircraft was written off (an A320 where the automation wouldn't permit the aircraft to flare for landing) and a number of incidents, without dredging up the reports notable events in Oz have been to a 777 and 330.
