I sure agree. I have a lot of experience automating things. There are
times when it's valuable to have something automatically activated, but
you have to be super thorough in examining all the potential faults. I
try to resist auto activation as much as possible. None on my plane.

It is extremely valuable to have computer monitoring. I've found Cozy
faults that no one knew about, just because computer was monitoring all
the sensors. Computer monitoring provides a leap in risk reduction. It's
pretty ironic that computer monitoring is lighter, less expensive, much
much safer, yet seldom done. I'm currently writing installation
instructions so people can buy off the shelf components, install safer
systems.
