ELI5: Will we eventually reach a point where we have "cured" most causes of death, or will they just be replaced with new causes?

Most causes of death are problems with cells aging and not reproducing properly, or problems with build-ups of substances such as "bad" cholesterol.

Once we fix that issue, we may find that new diseases spring up once you pass age 200 or so, but it's more likely that we will live until we have some accident or violent death.

Population control is less of an issue than you might think.  Already, the reproductive rate is decreasing.  More and more people are deciding to have only one child, or none at all.  If you think of the people you know who have a lot of children, chances are they are either doing it because of ignorance of proper birth control or a religious reason.  There are exceptions - people who just love having kids, but the people who have no kids compensate for them.
