As I stated earlier, the fact that there is normal variation in human language models makes it easier for a machine to pass the Turing test. However, a machine with a lossless model will still outperform one with a lossy model because the lossless model has more knowledge. I agree it is

However, a machine with a lossless model will still outperform one with a lossy model because the lossless model has more knowledge. PKZip has a lossless model. Are you claiming that it has more knowledge? More data/information *might* be arguable but certainly not knowledge -- and PKZip
