There are several technologies on the horizon that can change everything (as Steve Jobs would say)
Real virtual reality - For a big chunk of the world who need to see it to understand it, that will open the doors to a learning, design, and experiencing new things.
Carbon based circuitry - the first all carbon integrated circuit will be 10x faster and 5x more efficient than the best silicon out there. This will put even more amazing compute and sensory power into everyday devices. We chuckle at wizard's wands but they make for a easy to carry universal remote.
Graphene based charge storage. So often we throw energy away in friction brakes because that is easier than reusing it. Charging gear in seconds to run for hours. Recapturing more solar energy both from visible light and latent heat.
Fusion power for unlimited base load power. Completely re-defining the economics of industry, water supplies, transport, and urban HVAC.
Genetic designs, e.coli that synthesize chemicals of our choice without risky refineries. Curing genetic diseases not just treating them, repairing organs, limbs, brains, with targeted stem cells.
Robotic automation that can assemble or disassemble thousands of different products. Reducing waste, eliminating toxic dumping, and allowing us to get ahead of the clean up curve.
