i think png will never be replaced because you will always be able to tell that a png file is lossless, but jpeg is almost always used as a lossy format, and you will never be able to tell at a glance whether someone cared enough to make it lossless for a particular file

(note: losslessly preserving jpeg artifacts is still lossless if those artifacts were already present in the source material)

That's a good point, though image viewers could add that information to a "more info" dialogue.

i don't look at dialogs before i download, save, or pick a file from a directory listing

But you look at your image viewer that could have the lossless indicator? (and there is an issue open to add this indicator to the jxl files)

But you can't tell that png is lossless as you don't know how much loss there was before png
