Inside of you there are two wolves. Inside each wolf there are zero, one, or two wolves. Write a function to rebalance an arbitrary wolftree B such that it has minimal depth. The function should execute in O(logn) time. Show your work.

A(q, K, V) = V @ softmax(K / √d @ q)
Weights: K / √d and V
nonlinearity: softmax

i do think the degree to which bluesky is stressing that they do not use blockchains really underscores how toxic even a faint whiff of blockchain has become to any normal platform

Kid has an English assignment, where school has kids first submit essay to an "AI checker." Kid did not use AI. AI checker says the use of the word "devoid" magically turned essay into 18% AI written. Changing "devoid" makes it drop to 0%. We're spending time "un-AI-ing" an essay that has no AI.
