A recent article in a special issue of Popular Science mentions the Voyager Golden Records of circa 1977. Some of the content was plausible and might be intelligible if discovered by a technological intelligent culture. It seems very unlikely that the Voyager will ever be discovered by an ET technological culture, but the project was not costly compared to various questionable government projects. I think SETI projects are financed by private donations, so perhaps an it was a worthwhile project with an ultra slim chance of success. One set of data included was politically correct nonsense. It was a short greeting recorded in 155 languages. While a technological culture might be able to make sense out of some of the data, the decryption of that short greeting would be a miracle. Anyone with some knowledge of cryptology would know that there would be a slim chance of decrypting a message in a single language which was 155 times as long as one of the individual greetings. The same short message in 155 languages has extremely little, (likely zero) chance of being intelligible.
