Aubrey de Grey

Aubrey de Grey is a transhumanist and cryonicist who posits that the first person to live to 1,000 is likely already alive and that someone born around the year 2000 has anywhere from a 50 to 80 percent of living much longer than the current lifespan, depending on how much funding SENS and related life extension programs receive soon.

Criticisms
PZ Myers believes immortality is impossible because the second law of thermodynamics leads to inevitable decay in any living system.

Allegations of sexual harassment
In 2021, de Grey was placed on administrative leave by SENS Research Foundation over sexual harassment allegations. Shortly after, he was removed from his position as he seemed to interfere with the sexual harassment investigation.
