I find the concept of ethnicity to be weird and fuzzy at best. Like, even within my own country there's a whole bunch of different cultural sub-divisions (not talking about the russian army, obviously). West of Ukraine almost speaks a completely different language from Kyiv residents and might have more in common with Poles or Hungarians in terms of cultural background.
I think it's absolutely valid to claim Internet as your cultural background, but the label of "ethnicity" is not defined well enough to use it that way and people love to argue semantics.
My standards would have accepted a doodle made in Paint. This is lower effort than that, for way more computational power wasted (which, in turn, means more energy and heat wasted).
I have no issue with using AI in research and problem solving where it actually exceeds humans. For meme making, OP could have at least made sure it draws an actual hierarchy instead of every node connected to every other node. Or at least fix it in Paint afterwards.
"Straight" might be somewhat of a stretch
