well, high quality digital is a whole different game from film. in the 1980's the closest thing was a VHS camcorder and my 4k micro four thirds digital camera absolutely blows a 1980's VHS camcorder out of the water.

Yes the image quality of a 4K camera is technically less than that of a film video camera, but show a 1980's movie producer a digital workflow and their mind would be blown. You shoot the picture and can then immediately review and even edit.

So 4K video beats home VHS on quality by leaps and bounds, and for anyone who would have been producing video on film the workflow for digital is amazing.

Hmmm, a 4K camera that can fly around for 30+ minutes with a controller attached to your cell phone (which in and of itself would blow the mind of any person in the 80s) that has the visual clarity of an image shot on 35mm motion picture camera weighing in at 70+lbs that could only be used aerially by renting a professionally piloted plane/helicopter at more $$ per hour rental than the drone you fly on your own costs?

No, I can't imagine any benifits for modern tech from the 80s ;-)

depends what you mean by convenience. The image quality of a 4k camera isn't that much better, but that's largely because it doesn't need to be. Cameras in the 80s already produced great pictures. The difference is that they can weigh less than a pound and be run for hours at a time without worrying about paying ridiculous amounts for film.
