Automation because of safety, latest recent example, Boeing MCAS, cost savings led to airliners crashing, pilots didn’t complain enough then nor had the proper safety because Boeing.

You are not supposed to need all the “bells and whistles” to fly, a plane is a plane and a pilot is in left seat meaning to fly the plane. There are checklists and minimum equipment lists that state what is possible and how to handle failures and control.

You can not automate that, yet.
