Here's my take as a web developer from that article, who primarily cares about formats widely supported by web browsers.

For most purposes where I might use a PNG I might use a lossless WebP now because it seems like lossless WebP beats PNG pretty solidly. My take also is that WebP is a good JPEG replacement.

JPEG XL usually does better but practically that doesn't matter much because I think the only web browser that supports it is Safari

Of course there is a lot of politics around JPEG XL, specifically Google doesn't want us to have it and they're a monopolist so we can't have it. If there is any chance we're going to change that we're going to have document that JPEG XL really is better than the alternatives and your article does that.
