This was very much a case of a researcher finding an unnecessarily provocative way of saying that medical technology to date hasn't done much for the processes important in late-stage aging. Which is true. There's only one therapy recently in clinical trials to clear the transthyretin amyloid that appears to be the major cause of death in the oldest people. No other therapy really even touches that form of age-related proteopathy. So the present situation is quite consistent with the appearance of a maximum to human life span, and will continue to be so until such time as the medical research and development community actually start to meaningfully address the forms of damage and waste accumulation that cause high late life mortality.
