If we cannot reproduce research results, due to missing the data, parameters, or code, or whatever else, is it not cargo culting, to take that research result and blindly believe it and build on top of it? If I remember correctly, Feynman stated in the same video, that one should actually reconstruct or reproduce the experimental results we rely on.
