Do you mean robot fetishism as in android wives, or just people wanting to be cyborgs that don't need to sleep and are programmed to feel like they're on heroin 24/7? If it's the former, I can kinda understand where that's coming from.
Let's say tech arrives at a point where we can create android spouses that are indistinguishable from real meatbags. You can customize their looks and personality to be 100% what you want in a partner, and they will never say no to bending over when asked. You'd have to be crazy if you think that the average pleb isn't going to choose that option. It will record absolutely everything in your life and send it to some cunts in silicon valley though, so you'll never truly live a private life ever again.
I wouldn't say no to hatefucking Google, so I would try it at least once
