alt Hacker Newsof course these are all fairly controversial claims
- people dispute it compresses meaningfully better the types of images typically found on the web.
- progressive decoding is increasingly less useful on the internet as more and more connections become latency limited instead of bandwidth limited. jpeg & png (Although png's version has a cost i think) both support progressive decoding. However the last time i saw an image actually progressively decode was probably mid 2000s.
-flexibility in file formats is usually a bad thing. look at tiff.
personally i think jxl is massively overhyped. Its not horrible by any means, but its only marginally better than existing stuff, at best.
Disagree with the second point. For one, there are many parts of the world where bandwidth still is an issue, either due to lack of infrastructure or because common people in those places can't afford better connections. This isn't going to change any time soon because although given bandwidth goes up over time, so do the file sizes websites serve. And even then, I'm posting this through a super fast connection, with which I still occasionally experience loading issues when my VPN acts up, because I live in a place with extreme censorship - which is on the rise worldwide.
Generally, the approach should always be to prioritize files loading as fast as possible.
