I think that ideally, everyone would die by suicide. Everyone dies eventually and doing it yourself ensures that it is as painless as possible. Even if we hypothetically found a way to keep people alive forever I don't actually think most people would want it, pretty much every old person I've ever talked to said they wouldn't want to keep existing forever, oftentimes not even in heaven. So even though I know most won't see it like this, I see the fact that people are dying because they want to and not because they suffered horrific diseases that slowly degraded their body over the course of months until it eventually kills them, which is the way I think most people currently die right now, as a good thing.
It's just that it seems very tragic right now because most people who would commit suicide right now are doing it to escape some inescapable suffering, oftentimes that could be preventable if certain technology was available, or if people in general behaved different. But I actually think that the ideal is that 100% of people die by peaceful and painless euthanasia at the time of their choosing. I don't really see suicide as necessarily a disease that "takes lives" in the sense that it is undesirable, and I don't see it as something that should be "fixed" except in the sense that it should be more acceptable to receive assistance to make it more painless. The only thing I see as a problem is the preventable suffering that could drive someone to want to die in the first place.
