The X Prize is taking aim at aging with a new $101M award

"The winners will have to prove by 2030 that their intervention can turn back the clock in older adults by at least a decade in three key areas: cognition, immunity, and muscle function."

"To win the competition, teams have to develop a “proactive, accessible therapeutic” that improves muscle, cognition, and immune function by an amount equivalent to a 10- to 20-year reduction in age in healthy people aged 65 to 80."

It's nice to have optimism, but the fact that the therapeutic has to be "proven" in healthy humans (not animal models) by 2030, makes this impossible.
