Apparently someone is deep diving into performance edge cases. They (most likely with the help of ai or totally by ai) submitted a three line PR https://github.com/numpy/numpy/pull/30810 to speed up np.array_equal. Now the same author submitted a much bigger PR to speed up np.isin https://github.com/numpy/numpy/pull/30828. Is the work the product of ai? Yes, but the author claims to have verified the code. Is the author ai or not? Should we proceed with the PR? Matti
