During a recent video AMA called Longevity Meets Blockchain - AMA with Aubrey de Grey and Vitalik Buterin, Aubrey de Grey had stated,
A month or so from now, there's stuff I can't talk about, that is happening that will be really seismic in this field. Somebody whose name we all know, and whose name I cannot mention, but who has been talking to me and has been interested in this for more than 15 years is finally going to be doing something.
Some people on Reddit speculated that Aubrey de Grey was referring to Jeff Bezos. One commenter stated,
Aubrey met Bezos at Ted back in 2006 (15 years ago), and Aubrey did mention that this person has known about Aubrey for 15 years. Bezos just "retired" recently as well.
Jeff Bezos has been interested in longevity before. In 2018, CNBC reported that Jeff Bezos was among the investors who backed Unity Biotechnologies. It's also true that Jeff Bezos announced his retirement from Amazon on February 2nd of this year.
