I have exactly the same thing. Most tinnitus is caused damage to the hair cells in the cochlea from loud noises for extended periods of time (as is mine). My theory is that the brain basically turns up the gain to compensate for the poor performance of the sensor. I think tinnitus is basically interference, or cross-talk from other nervous processes that normally are low level background.
Last time I went for a hearing test the doctor asked me if I had been in an explosion (not to my knowledge).
They'd bring to the table having been CEO and CTO of OpenAI. That's a lot of relevant knowledge and experience (the latter being the more important in this case).
I'm not seriously proposing this, but what if the "subconscious" (whatever came up with your obstetrician names without you perceiving it) is actually another consciousness, "locked in". Perhaps there is another story here, where a dream was had about a party, and the observer felt they were coming up with humorous names for an obstetrician.
In a similar vein, I find trying to explain something to someone gives you a good feel for how well you understand it. Often I find that I don't understand things as well as I thought after such an exercise.
"This is not an unreasonable thing to do, given that they have a global audience"
Clearly that was not their motivation. In fact I'd argue that it's the global audience that were most annoyed by this.
