I'm of the same opinion. I love getting feedback, better if it's constructive, but all kind of honest feedback is useful and welcome. And it doesn't always come from people with more experience, sometimes a greenhorn will see things that a greybeard like me doesn't.
But I've seen people giving negative responses to the best feedback. Hell, I've had people complaining for hours because someone else replaced their manual process that took an hour to do with a script (and copy&paste of the result) that took literally seconds to run.
Yeah, I've seen that as well. I believe it's mostly fear-driven, in a way of "if this gets automated, why would they need to keep me around". It's a terrible mindset for everybody involved. It really slows the team down, and it's a major issue for the person themselves. It's like impostor syndrome on steroids. Not only do they worry that they might be found out, they worry they might be replaced by a script.
I've never personally seen somebody getting fired because a script can do their job. I've seen them being freed from doing the same repetitive bullshit day after day though, and finally being able to actually tackle new challenges.
But unfortunately, that kind of mindset is not something you can change through rational arguments, at least in my experience.
