Thanks for reminding me of the word plinth. I agree with the author that the job is less fun now, less interesting. I'm doing and accomplishing more, and it matters less. And unfortunately, having other ways of defining your identity doesn't really help, for me. What it does is make those other aspects of myself relatively more attractive as careers, in comparison to this one. Although then again, I suppose it's helping in the way you intend: I could leave (and I might), I could adapt. So I'm feeling none of the fear or anxiety about AI. Just something that I think is roughly boredom.
