I've been coding for 20 years too and I'm also open to new things. But no one can be proficient in everything anymore so there is a cost to learning something new: we have to forget something we previously spent time to become familiar with. Don't be sad, it's clearly a natural reaction that has some utility. I agree that there's a better way to phrase it, usually something like "is it really that much better than what we have now?"
