Wars, disasters, and deliberate erasure have destroyed countless historical records, leaving gaps and disputes that may never be resolved. Better methods for reconstructing or verifying history could settle long-standing disputes.

The first hours after a disaster are often the most critical for saving lives, yet aid frequently takes days to arrive due to logistics and coordination failures. Closing this gap could save many lives that are currently lost to delay alone.

A language disappears roughly every few weeks somewhere in the world, often taking irreplaceable cultural knowledge with it. Without better preservation tools, much of human linguistic diversity may vanish within a generation.

Justice systems around the world vary wildly in how harshly they punish the same crimes, reflecting different beliefs about what punishment is actually for. Whether punishment should aim to rehabilitate, deter, or simply punish remains unresolved.

Different cultures, religions, and individuals define meaning and purpose in very different ways, with no way to prove one view more correct than another. This makes questions about how to live well deeply personal rather than settled.

If AI systems ever become capable of something like suffering, we would have created that suffering deliberately, and we don't have a moral framework ready for that possibility. This question is likely to become urgent faster than expected.

Some countries and individuals consume vastly more resources than others, and there's no broadly accepted definition of what a fair share would even look like. This makes global cooperation on resource use difficult to justify to everyone involved.

When an autonomous system makes a harmful choice, moral responsibility is hard to pin on any single party, the programmer, the company, or the AI itself. Ethics hasn't caught up with the reality of decisions made without direct human involvement.
