Anecdotally, the common theme I'm starting to hear more often now is that people who use “AI” at work despise it when it replaces humans outright, but love it when it saves them from mundane, repetitive crap that they have to do.
These companies are not selling the world on a vision where LLMs are a companion tool, instead, they are selling the world on some idea that this is the new AI coworker. That 80/20 rule you're calling out is explained away with words like “junior employee.”
I think it's also important to see that even IF there are those selling it as a companion tool, it's only in the meantime. That is, it's your companion now, but because we need you next to it to make it better so it can be an "AI employee" once it's trained from your companionship.
