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 That a tech innovation really helps us safe time. As someone recently pointed - I forgot who it was -, for at least 20 years every single innovation in tech promised to free up our time for what‘s really important. Instead we work ever more trying to keep up with all the different channels we need to satisfy.
