The quality between the two formats is stunning... BPG version looks blurry compared to the mp4 version.

Author says that the BPG version is re-encoded from the MP4, so lower quality is to be expected. Looking at the linked comparison tool[1], it seems that while BPG and WebP both have fewer artefacts than JPEG at a given file-size, BPG seems to achieve this with waaaay too much smoothing. Seriously, check out the engineer's eyelids in [1].

Wow, this throws me back to the early 90s, when we would basically have the same discussions about JPEG vs GIF. At the time most graphics programs could open a GIF you downloaded with your modem, but if you wanted to view a JPEG you had to jump out to a separate program, and everyone said that as soon as there was native JPEG support no one would use GIF anymore.

How can a lossy format replace a lossless format? The author clearly doesn't know what they're talking about.

Because the internet doesn't need a HUGE lossless animated image format. What it needs is something GIF-like (animated images with no sound) that works universally, is smaller, and doesn't consume too much battery on mobile devices.

So BPG (or others) could replace GIF for the way GIF is commonly used today, rather than a direct 1:1 drop in replacement in all scenarios. If you really need lossless then continue to use GIF, support isn't going away soon, but for small soundless animations, a better alternative may be welcomed.

PS - The statement "The author clearly doesn't know what they're talking about." is inflammatory and needless. The author never said anything either way about lossless/lossy.

If people said that then they were silly, because JPEG and GIF solve different problems. JPEG didn't displace GIF because JPEG doesn't actually do a good job of compressing the images that GIF is good at compressing. Note that once a format came along that was good at those, namely PNG, it did displace GIF pretty much entirely for the still-image use case.
