An utter derailment of this thread, but this claim seems to me a massive departure from my understanding of information theory. I am put to mind of the fable of the 1-bit image compressor, which can compress any image to just 1 bit; its decompression algorithm checked if the input bit is a 1 and if so, emitted the Lenna test image, and if the input bit was 0, would fail with a decompression error. Since the only requirement for publication in a journal is to be able to correctly compress and decompress the Lenna test image, the image compressor achieves 1-bit compression of any image, as shown by the successful compression and decompression of the Lenna test image. I wonder if the blockchain data is stored in the tweet, or in the AI that decides how to store it in the tweet. Regards, ZmnSCPxj
