Slavery. Organized crime. Corruption of governments. Imperialism. Economic inequality. Nuclear proliferation. The coming waves of climate refugees. Insufficient water. The coming crop failures in about a decade that will kill 1/4 of the world's population.

    ..and loads and loads of politicians that pretend they can solve problems above while shamelessly grifting.

Peak oil. Everybody stopped talking about it in the late 00s when it was discovered that shale wasn't inaccessible after all, but now every shale patch except the Permian has already peaked and the first derivative of the Permian output is plummeting.

The greatest technical ones are:

- Countering aging / human rejuvenation.

- Atmospheric carbon capture and utilization.

- Strong materials / bringing materials up to their theoretical strengths. (The theoretical strength of fiberglass is ~40GPa; the best samples generally measure at ~5GPa.)

Yet it's the non-technical challenges surrounding governance, how to handle social media, how to deal with falling birthrates, etc., that are much more pressing.

All humans die, and IMO it's just a knowledge issue. We probably have sufficiently advanced tech to implement a solution.

    While I'd really, despereately like Washington, Adams, Jefferson, Lincoln and many others to be here today to give opinion,

    do not forget death is not just a problem but also a solution.

      Yes, it has ramifications in every direction of course.

      I suppose we'll still kill each other, even if medical advances make unintentional death unlikely.
