To be honest, hand wringing over “clanker” being a slur and all that strikes me as increasingly equivalent to hand wringing over calling nazis nazis. The only thing that rubs me the wrong way is that I’d prefer the new so called slur to be “chatgpt”, genericized and negative connotated.
If you are in the US, we’ve had our health experts replaced with AI, see the “MAHA report”. We’re one moron AI-pilled president away from a less fun version of Skynet, whereby a chatbot talks the president into launching nukes and kills itself along with a few billion people.
Complaints about dehumanizing these things is even more meritless than a CEO complaining that someone is dehumanizing Exxon (which is at least made of people).
These things are extension of those in power, not some marginalized underdogs like cute robots in scifi. As an extension of corporations, it already got more rights than any human - imagine what would happen to a human participant in a criminal conspiracy to commit murder and contrast that with what happens when a chatbot talks someone into a crime.
And yet you are the one person here who is equating Mexicans and Black people with machines. People with disabilities, too, huh. Lemme guess next time we're pointing and laughing at how some hyped-up "PhD level chatbot" can't count the Es in dingleberry, you'll be likening that to ableism.
When you're attempting to humanize machines by likening the insults against machines to insults against people, this does more to dehumanize people than to humanize machines.
edit: Also I never seen and couldn't find instances of "wireback" being used outside pro-bot sentiments and hand-wringing about how anti bot people are akhtually racist. Had you, or is it all second or third hand? It's entirely possible that it is something botlickers (can I say that or is that not OK?) came up with.
edit: especially considering that these "anti-robot slurs" seem to originate in scifi stories where the robots are being oppressed, whereby the author is purposefully choosing that slur to undermine the position of anti robot characters in the story. It may well be that for the same reason that author has in choosing these slurs, they are rarely used (in the earnest).
