I haven’t had time to read through the entire article, but I most definitely need to. Quickly skimming over it, this jumped out.
Those of us who have been around for awhile have hundreds or thousands of Type 1 PostScript fonts. Converting them as needed to OTF or TTF will be a huge pain in the butt. Using those converted fonts will be another ugly RIP choking issue.
I don’t know if the article addresses this, but the increasing number of required system fonts and all the worthless (to me) extra fonts that are installed are really turning into a major annoyance. Having to scroll past hundred of fonts in a junk drawer of debris to get to the one font that I need is starting to make me very angry with Apple.
I have many thousands of type1 fonts (and a few hundred type3 and other non postscript fonts but let’s not go there). I will be investigating any decent conversion utilities that appear, but only for use on legacy jobs and only as and when they come up. I mostly use TTF and OTF fonts these days.
