In the perhaps not so distant future, surgeons could perform a range of medical procedures all without touching the patient, thanks to advancements in 'acoustic tweezers'. These were the kind of things I was excited to read as a kid; not some SJW/NPC nonsense of some communism/wealth redistribution scheme. Good things are still happening around us and science is still improving and expanding. It's not very long ago we heard about optical tweezers which ended up with the Nobel Prize for physics.
