In a new video posted on his YouTube channel, Johnson revealed a significant error concerning rapamycin, a immunosuppressant, popular in anti-aging circles. Johnson modified the dosage after testing and reseraching on rapamycin to manage potential benefits and risks. However, instead of experiencing rejuvenation, the tech entrepreneur began noticing side effects.

Johnson experienced several adverse effects, including mouth ulcers, slow wound healing, cholesterol imbalances, and elevated blood sugar levels. Additionally he also experienced an increase in his resting heart rate.

As Johnson puts it, Don't Die is a "universal translator and the grand unifying theory of existence." He said that with democracy governing civic matters, capitalism dictating wealth and religion caring for the soul, "existing frameworks are too narrow". Instead, he proposes his religion, which he claims "speaks fluently with...+ the universe through physics + AI via mathematics + software via computation + living things via biology + humans via storytelling + truth via memetics".
