I agree wholeheartedly. Computers can do the wrong thing at incredible speed sometimes. This reminds me of the anecdote that nuclear submarine designers knowingly don't automate some things because if the automation would fail then it would cause the loss of the entire sub quickly enough that the situation is beyond salvage by the time humans can react. Instead, they have an extensive checklist and do all procedures with 2 people and a third over an audio line. Even if it does go wrong, it will probably go wrong slowly enough that a concerted damage control effort from the rest of the crew can contain the problem.
