What technological or medical miracles are we likely to see in the next 20 years?

I'm pretty sure there's gonna be robot maids floating around in space hotels in the next twenty years......that's not medical but it's important. A few months ago I thought the floating maids would be human ... But I decided the shouldn't have to deal with all that floating Spoodge. Robots then.

Mechanical hearts and lungs.
Petri dish grown body parts.
3-D printed food.

I think there would be improvement in Nano technology , there would be a technology where mind uploading in computer can be done , so we can be still immortal , still we have hope in cryonics and also biological immortality , after that humans and animals would tend to live forever , there would be no place on earth , so humans would find other planet to live in .

Dear Didge,

I think we will see tremendous advances in human psychology, for example treating and understanding trauma. Maybe fractals will be involved here... human systems and even the brain as fractal in nature?

Already there are recoveries undreamed not that long ago.

AI, or a form of AI

The human race is going to Mars, which isn't really a breakthrough since the news is old, but it's pretty amazing

Virtual reality will become more widespread

I don't think there will be a cure for cancer, as it is too broad of a disease. For example, there are seven different types of breast cancer and one of them has six subsets to it. I am hoping there will be better ways to detect and treat each cancer.
