I feel like the right answer to that is to make ghostscript run on a cell phone. I mean... we're already on Darwin or Linux; the userland is weird, but ex. Termux and iSH proves that you absolutely can run a lot of packages all the same. So in my mind, the real question is: Why does the porting and app development experience suck so much? I mean... HyperCard, in 1987, was usable by non-programmers. A/UX had Commando in 1995, which wrapped CLI in a nice GUI. To hear people rant, the height of RAD GUI building was Visual Basic 5 (1997) or VB6 (1998). Have we really lost that much in the ensuing 25 years?
