- A participant criticized a self-experiment in which the author encoded Hebrew text into DNA, pointing out that the “codon” mapping is a naïve one-to-one substitution of Hebrew characters to DNA bases, making the sequence non-reversible and demonstrating a fundamental misunderstanding of coding theory.  
- The same critic emphasized that such a flawed encoding scheme undermines the integrity of any data storage or retrieval effort, even though the technical execution of DNA synthesis itself was successful.  
- A link to the 2006 MIT Voigt-lab paper “Environmentally Controlled Invasion of Cancer Cells by Engineered Bacteria” was shared, describing a synthetic-biology approach that programs bacteria to invade tumor tissue only under specific environmental cues.
