IVRs suck, though I know of a few that have interesting behaviors. There's one that a bank uses which will automatically get you a human if you say Fuck or bullshit to it. I'm sure they have plenty of recordings of me saying "fucking bullshit" just to get a rep.
Yes, IVRs suck. They make some things that should take 10 seconds take a few minutes. However, trying to push a sexism angle because IVR's are god awful is pure Bay Area intersectional stupidity at it's finest. What's next? Soft keyboards are ageist or ableist because they require a good amount of dexterity to use?
