Blade Runner's production design is beautiful and almost prefectly timeless in its depiction of a future. The only thing that dates the film for me is the cathode ray tubes. They are even in the flying cars I think.
Directors and designers could start using flat blue devices so that interfaces can be re-imagined, in 2-D, or 3-D, and composited in future re-masterings. I like the non-desript tri-fold devices in Westworld. Kudos to the 2001 team for getting imagining tablet interfaces although that did not sway the jury Samsung vs Apple iPad case[1][2].
