2050, anyone?

Here's an assertion: a list of advancements I expect to see in the next 30 years. These are technology advances that push the boundaries of what's feasible. The gap between the feasible and the current is not the topic here. As a result, already-feasible items like solving water shortages are not in this list.

The structure of this list is to state the boundary that's being attacked and list a few methods that are attacking it.

1. No shortage of materials
1. New materials from the labs, continuing the tradition of metallurgy & materials sciences
2. Nanotechnology and bio-mimicry to get new properties in existing materials
3. Better mineral discovery and extraction on Earth
4. More minerals from mining asteroids
2. No shortage of energy (primary and stored energy)
1. Primary energy
1. Small modular conventional nuclear power plants
2. Molten salt thorium cycle nuclear power plants
3. Fast breeder nuclear power plants
4. Bugs that create fuel (e.g., "oil from algae")
2. Stored energy
1. Ammonia or other man-made nitro-chemicals used as fuel
2. Better batteries (liquid, solid-state, etc.)
3. Brain interfaces with technology (TV remotes, computer keyboards, prosthetics, war-machines, brain-to-brain connections, etc.)
4. Ubiquitous high speed telecom
5. Virtual reality and mixed reality (augmented reality)
6. Lots of AI (intelligent assistants)
7. Life-extension technologies
8. Personal-capability enhancements (prosthetics, genome, drugs, bugs/biome, etc.)
9. Garbage/waste elimination (recycle/reuse/re-nature)
1. Recycle fertilizers, nuclear waste, etc.
2. Reuse metals, minerals, etc.
3. Re-nature (degrade back to non-toxic chemicals) drugs, plastics, etc.
1. Bugs/plants/fungi that eat plastics and other currently non-degradable materials
2. Biodegradable materials
