> If JPEG XL doesn’t become useful on the web, is it really likely to become popular with camera manufacturers, professional image editing tools, etc?

I suspect that eventually, the browser makers that are reluctant to add JpegXL support will do so, even if reluctantly, and so it will eventually "become useful on the web".

The reason why is Adobe added JpegXL as a compression format for PDF's, and as every browser maker wants their browser to also be a "PDF viewer", this means they must include a JpegXL decoder to be able to support PDF's going forward. If they must have a JpegXL decoder anyway, it is not that difficult to also add it as another supported format for the <img> tag.

Looking forward to a future where we can arbitrarily DoS anyone with a PDF that computes massive swaths of prime numbers.

		You used to be able to DoS the user's browser by sticking thousands of tiny animated gifs on the same page. You can't do that any more (AFAIK) because that's a bug so the browser developers fixed it. This is the same thing. It's odd that apple didn't proactively guard against such concerns when adding a new format.

		PDFs can already do arbitrary computation. You can even play tetris in them.

		Can't that future adopt basic resource / complexity limits to defuse the DOS bomb?
