I understand bottom of oceans have huge pressure differentials and lack of light.
However I don’t see why we can’t use two fiber optic cables (one for light one for camera) to explore the bottom of the ocean. When I say fiber optics for camera I mean the slender cameras they use during surgeries.
I’m sure these strands of plastic/glass can handle way more pressure than human body or metal submersibles.

They’re hard to manuever and the sensors are too small to record the very little amount of light there, so the images will be noisy, then the water at these depths blocks a lot of light, and the ocean is too big.
What they can use to get very high resolution pictures of oceans is specialized sonar devices which bounce sound waves around.
