Context: Even though Chromium has native support for AVIF, a very nice image format, Microsoft goes out of their way to remove it from Edge, which is a chromium fork. Jpeg XL (JXL) (not to be confused with Jpeg (JPG) or Jpeg 2000 (jpg2k) ) is another nice image format, which, IIRC, is only supported in Firefox.
WebP cause small size, can be transparent, can be animated, can use either loseless and lossy compression. Also it pisses of many people which is funny to me.
Do you write postscript by hand? I once got the change to take a postscript programming class, but sadly I didn't (I wish I did tho). How does it compare with SVG? I know SVG has a lot of limitations (for example, you can't change the color of a shape filled with a pattern), so I guess eps' turing completeness lets you overcome things like that, since you can just program in whatever functionality you need?
