Ask HN: What tech that's right around the corner are you most excited about?

Regrowing teeth from your own stem cells - but that seems on the same timeline as fusion.

Improvements in construction.

Affordable housing that is really affordable (ex. subsidized is not affordable.) Being able to build nuclear power plants on schedule. Things like that.

Flying cars. Open-rotor engines. SpaceX Interplanetary Transport System. Skylon/SABRE rocket engine.

Self-driving cars obviously. They will change so much! More practical applications of gene editing.

Definitely yes self driving cars - I'm sick of road rage. Also hopefully more efficient petrol and electric will dispose of filthy diesel.

There's also some interesting developments in improving maritime transport efficiency.
