WebP should not have been released and no one should have used it. Google should stop letting individual employees invent new image formats as hobbies. (This happened _twice_. WebP lossless is a whole different codec from lossy.)

AVIF is the first one that might be acceptable.

Another take on this:

AVIF is a Netflix engineer quick-hacking a video format as an image format -- without actual experience in codec design, image compression or psychovisual research, without consulting such people to get the design right. When size and memory limitations were noticed, a tiled approach was proposed where globally spanning artefacts through the image will emerge. No one has been able to propose a fix for this and other kludges yet.

AVIF doesn't match WebP lossless in density, even given the 10 years more of compression research. AVIF doesn't even beat PNG at lossless, which itself was hacked together in a few months ~25 years earlier (primitive filtering, mixing filter bytes with image data, botched 16 bits compression, layering a primitive 1980's byte-compressor and filtering instead of designing a codec).

I am glad I am not the only one seeing it. While in extreme minorities, still happy to be this view is not some insanity as many claims to be.
