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

@Garwboy
Cure for x kind of cancer
@flcardiacnurse @Garwboy they're not promised. Not by scientists doing the work. Maybe by journalists.
Some types of cancer are curable.
Some still aren't.
We always need better tests and treatments, incremental progress is still progress.
