No, I can't imagine any benifits for modern tech from the 80s ;-)
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.
Anyone who doesn't experience a genuine "Holy shit, I'm actually living in the future" moment when they first encounter a Mavic Mini or similar modern consumer drone is probably in need of pharmaceutical help or talk therapy.
