With Latex, we have a powerful tool at the hand which makes sure every single student can write himself a perfectly shaped PDF which looks timeless.
It doesn't even matter whether your favourite open access journal renders the paper as HTML -- they only took the Latex and transformed it.
It also doesn't matter that we have meta search engines for literature references (for instance http://inspirehep.net/ or https://ui.adsabs.harvard.edu/), or that we do have archives for uploading scientific data (https://zenodo.org/ or in general https://www.re3data.org/): The papers are still non-interactive, still linear (not clickable hypertext).
Science is old fashioned and slowly moving...
