He put in way more work than would've been necessary to get StyleGAN or CLIP to do a vastly better job, is my point, because he used totally the wrong tools and approach. (And he could put in vastly more work, and it still wouldn't work that way either; the level of effort one would or would not spend on a SIGBOVIK paper is just irrelevant when his approach is doomed from the beginning.)
To be fair, this was for April's fools, he probably did not intend to get something actually usable (as far as upperercase letters can be usable) .
