Longevity entrepreneur and biohacker Bryan Johnson has once again sparked debate about the future of human life, declaring that "some of us will live forever" as advances in biotechnology and artificial intelligence accelerate efforts to slow, stop, and potentially reverse aging.
In a lengthy post announcing that he had renamed his company to Immortals, Johnson argued that humanity is approaching a future where increases in life expectancy could outpace the rate of aging. According to him, this would mean people may no longer be expected to die from natural causes by default.
While acknowledging that the idea sounds radical, Johnson said his optimism is based on three key developments already taking shape in science and technology.
1. Immortality already exists in nature
Johnson pointed to examples in biology that suggest aging is not an irreversible process. He explained that when a sperm and egg combine to create an embryo, the biological aging clock is effectively reset to zero despite originating from parents who have aged for decades.
He also highlighted the famous Immortal Jellyfish, a species capable of reverting its cells to an earlier developmental stage and restarting its life cycle. Scientists, he noted, have begun exploring similar concepts through induced pluripotent stem cells (iPSCs) and partial cellular reprogramming, techniques that have shown the ability to reverse some signs of aging in laboratory settings.
2. AI is unlocking new possibilities
According to Johnson, biology has traditionally been too complex for humans to fully understand and manipulate. Artificial intelligence, however, is beginning to change that equation.
