Right now, human lives are still capped at ~120 years, and usually much less than 100. In the (mathematical) limit, each person will die of a unique cause at age infinite. While we won't ever reach that limit, it's worth to continue getting closer to it.
Maybe the fact I don't actually makes it easier to understand biological complexity.
You guys have to figure out how to fix a brain when it breaks.
In CS, a holy grail is to match or exceed human cognition with general AI. It's not fixing something broken, its reverse engineering or alternatively engineering from scratch the greatest known computational device in the universe which has evolved over a billion years.
It's often not appreciated that this hasn't happened yet not due to lack of computing power. It hasn't happened yet because we're still not even remotely close to knowing what code to write if we did have 10,000 times more compute. We don't know how to do it, and instead are forced to plod along in awe as every year we learn a little more about what we don't know.
I'm guessing you don't work in the medical field (I have). First their's the emergent complexity of scale (after all the universe consists of a finite number of a small number of fundamental particles). Second, the human body (and all the pathogens etc) are object code highly optimized over billions of years. We understand almost nothing about how it all works. We can transcribe most of a human's genome but barely understand how even a tiny part of it works.

The most common causes of death have been pretty much eliminated in the wealthy world over the last 50 years. People still die, just of a wider variety of less common reasons. In the limiting case, each person will die of a unique cause.
