Request for the hivemind

I'm looking for more examples of things/breakthroughs that are always 'imminent', e.g. predicted 'within the next 5/10 years', but thus far have not happened

So far I've got
- Nuclear fusion
- Quantum Computing
- Self-driving cars
- Canaverro's head transplant

Artificial General Intelligence (AGI),
Flying cars / personal air vehicles,
Space tourism,
Anti‑aging / longevity breakthroughs,
Cryonics(the revival part),
Cloning humans (although thankfully ethically stalled),
Cold fusion (since late 80's i think),
Hydrogen powered cars (at scale),
Carbon capture (again at scale),
Holographic displays,
Cashless societies,
Paperless offices (personally heard this one from 1987 - the day i started office work),
Moon colonies (or Mars)
