If the solution actually was "just use REM" there'd be no point, as you could create a browser setting that does px->rem on all pages, as this is how the font is scaled in the first place.

If you really care about accessibility you'll be using REM where it makes sense (fixing padding/margins that surround text), and not just by default like the article suggests.
