True, but that definitely wouldn't stop Oracle from suing over it anyway. (See the rangeCheck chapter of Oracle v Google [0])
Also, Oracle v Google opens the possibility of a fair-use defense in the event that Copilot does regurgitate a small snippet of code.
I say dumb because I am, perhaps chauvinistically, assuming that no brilliant algorithmic insights will be transferred via the AI copilot, only work that might have been conceptually hard to a beginner but feels routine to a day laborer.
Then again that assumption suggests there'd be nothing to sue over.
