I started writing my response in the tags, but actually want to save it for future reference.
anything rice does, bread can do better. accompanying curries ? I'd rather do naan, paratha or roti. with stews ? dumplings, dombolo, knödel. or lavash or injera. or even just any homemade bread is great (or mashed potatoes, pap, polenta etc. but that's outside the scope of this poll) there's no need for rice.
one of my favourite dishes in Chinese cuisine, genuinely and sincerely, are the scallion pancakes, which are a flatbread. (otherwise I prefer noodles over rice). oh ! and those long fried dough vetkoek-like things. also a bread and also delicious.
I'll concede, bread cannot replace rice in sushi. but you can eliminate rice and still have sashimi, so that's not really a point in rice's favour either.
how would rice respond to focaccia ? or to brioche and challah ? what is rice to pretzel and garlic bread ? to banana bread ! grinding rice into flour to make gluten-free bread is still bread. and pizza ! hello !? rice doesn't come close
