The opposite. CEOs necessarily need to trust others to do things because CEOs themselves don't have the ability to do the day to day work of a company.

So the first people who'd be overly trusting of things they don't understand would be exactly a CEO.

I would assume the competency of a CEO is in knowing who to trust and what tasks to delegate to whom. They appear to have failed in this regard.

They may even have the ability. But unless you're running a very small company, they don't have the time to do actual things.
