Grand problems for any decade until there are figured out.

- General artificial intelligence - being able to effectively model how the world works, and search for solutions in that model.

- Energy - nuclear fusion, cheap artificial photosynthesis, cheap solar such that we can have solar on almost every surface facing the sun.

- Molecular assembly - figure out how to custom program DNA from scratch to build what we need. Imagine building more efficient trees where it captures CO2 and sunlight into gasoline, or strong timber directly.

Each of these can go quite wrong if not developed with safety in mind.

I call it the Mind (intelligence), Body (molecular assembly), Energy (putting energy to work) problems.
