What about convection? There's been at least some mixing, right? So I'd guess the average age of a nucleus from the core (ignoring fusion) would indeed be less than from the surface, but I would think it's less difference (on average) than the raw math. If there's enough mixing it could be very little difference at all.
It's a lost cause, so I've nearly given up, but I still give 1-star reviews to apps that don't work because my phone is rooted. Every time they update.
It's really cheap to use a WAN model (or whatever the latest thing is) on my laptop to make porn without needing to find and hire a model, or even subscribe to an onlyfans. Also not paying OpenAI or anyone else besides the electric bill.
I don't think that's going away, and I would be a bit surprised if it's not already cutting into demand for the real thing (which I also think isn't going away)
Huh. Today I learned that it's not just English slang. It's from the language of the planet Ork.
