whenever a new video-generation model comes out I check if it can create centaurs from the prompt 'half-man, half-horse'.
The answer is almost always 'no'.
This is Veo 3.1's response to "a half-man, half-horse creature running along the beach"
The answer is almost always 'no'.

Personal Statements, Addendum:
some are written as if the applicant is a passive object that greater forces act on:
"I was led to X | this moved me to Y | I become fascinated by Z"
I encourage you to position your "journey" as an active choice, with you as the agent that makes the choices.

I again caution that that advice isn't meant to fit everyone; personal statements ARE personal and used differently (or not at all). I am only addressing a specific thing that I sometimes see students facing, when they think it HAS to be about challenges met and overcome.

I proposed these names for new AI-induced Psychoses a few months ago as a joke but the emails I've been getting have pushed me to think Banotti Mania may actually be a thing
AI heralds a golden age for clinicians who want to name new disorders; just throwing some out there:
Fournier Jitters: a particular form of anxiety, in which the person affected cannot make a decision or voice opinion without checking first with an AI assistant

A chiliagon is a 1000-sided polygon, famous in philosophy for Descartes using it as an example of the diff b/w imagining something visually and conceptualizing it.
Anyway I tried to get Gemini to draw it

can we all agree on a short designator to the paragraph "LLMs have proven surprisingly useful at (X), but are still not great at (Y), and we don't uite understand what's going on" and just move to using that?
Feels like it would save time/space for many papers to both Reader and Writer.
