It is really hard to say just one thing but if I could only name one I would say find a cure for cancer. That in and of itself would have wide impact on families who are emotionally and financially devastated as a result; should help reduce the cost of healthcare overall given that cancer treatment is exorbitant; and would allow researchers to focus on other illnesses or worldwide problems.

"Cancer" is such a broad term, with ~200 different "types". I agree that "cancer" is a huge problem (my brother had childhood leukemia at 9 months until he was about 6 years old), and its effects on the family cannot be understated. Unfortunately, we've only begun to scratch the surface towards a cure for very few of the 200 types of cancer out there.

That being the case, we still can't rule out the possibility of general-purpose treatment methods.

What do we do about population control when we have cures for diseases and better health care that extends the life of everyone?

We're already having a hard enough time with crops for coffee, avocados, and more due to high demand and climate change.

Once we move on to stabilizing the health of everyone we will focus on consolidating the infrastructural dross that takes up the space around us. I believe that house sharing will be a major thing once we all realize what we are here for and how perfect things could be.
