If you zoom in on a picture, the resolution drops rapidly. But the resolution of a picture or movie can be increased (such as a 4K upgrade) so could we eventually see very small or even microscopic things in old pictures or movies if the resolution keeps getting upgraded?

No I wouldn’t think so. You can only see what’s visible in the original. Imagine you took a picture of an ant from 50ft away at 8k the any would still only appear as a small dot. Then take another picture at 50ft with 100k the ant would still only appear as a small dot. Without zooming in to capture the detail no matter how many pixels you make a small dot out of it will only ever be a small dot. Resolution allows you zoom in on a picture and see little things, that were already there and defined more clearly.
Another probably better example, if you took a high resolution photo of a tree you could not zoom in and see the veins of a leaf, because they weren’t visible in the original photo. Now if you zoomed in on every part of a tree and compiled it into a high resolution photo you could do just that.
That’s the way I understand it. Someone can probably better explain the technical way
