I'm assuming you're trans and you follow or know people who seem to really care about these issues. I think you might be deeply biased, I search for the ChatGPT voice on Google and no one really seems to care about it in a negative way, if there was an actual backlash I would be able to find it easily.
>In my opinion, they should have hired a trans person, created a gender-neutral voice, and used that as the default.
I think the vast majority of the population would find it more natural to have a female or male voice. I also believe that people should be hired for their skills, not their gender.
