Because "Yeah, fair pushback" is AI smell. Either everything this person does is passed through an AI from code to blogs to even their HN comments and submissions; or they use AI so much they're starting to talk like it colloquially. Either way no one has time for that.
"Yeah, fair pushback"
Really hard to tell. Because that used to be a common phrase that real people would use.
So now I have to change my own language in order to not appear like I'm an AI? We are getting in a weird place where Humans have to act/sound increasingly 'odd', to appear not 'perfect' like an AI.
