I am thinking if H.264 AVC will be like Jpeg, where the worse is actually better. They are ubiquitous, and hardware decode in visually all Smartphone, and seems to be good enough for a lot of cases (non-4K usage). But it is still nice to see AV1 coming along, especially coming from VLC (dav1d) and Xiph ( rav1e ) .
Personally I find 1080p not enough nowadays.
That typo in the first bullet of the "Release" section is really bothersome to me oddly. Less know ones... less know... know... blah
That's the trouble with spellcheck. It can't tell you that you are using the incorrect real word.

Agreed, but I'm very curious which codec (h265 or av1) will eventually "win" in the 4K+ and HDR space.

I believe the compression benefits of AV1 to H.264 are greater than Jpeg to newer versions of image compression. Also, when you're talking about video, the sizes of files are magnitudes greater than images. I believe as long as we achieve backwards compatibility and easy conversion of video files, AV1 will be the future.
I think your second point is more important though. There are basically two main cases for images. On the one hand, you have images which are an input to some process, like editing or publishing, where people are unwilling to sacrifice any information, lest the errors accumulate. On the other hand, you have images intended for final consumption. By modern standards, those images are already so small that saving 50% isn't usually worth either losing compatibility, or putting in extra effort to offer a fallback.
There are some in between niches of course. Apple has bet on one in iOS with phone photography. That makes sense because many people will have a large volume of images, but they're not professional photographers who need perfect fidelity. I don't know if that's actually worthwhile to most users, though, since they too have to deal with the compatibility issue.

It depends on the target bitrate, but from what I've seen at high quality, the difference between HEIF and JPEG is comparable to the difference between H.265 and H.264.

I fully expect AV1 to become the new 'de facto' video format on the web which is the crown h264 has held for ages. No royalties, better compression and wide hardware support coming will make it a very attractive choice.
And as streaming will also move towards 4k+, given that all the streaming giants (Google, Netflix, Amazon) are directly backing the development of AV1 it would surprise me if they did not phase out HEVC in favour of AV1 for all their 4K+ needs as well (Youtube doesn't support HEVC at all).

Perhaps AV1 will in the loooong term, but as of today h265 is what every 4K Blu-Ray uses and just about every modern device has a hardware decoder. So that’s gotta count for something.
The only way to relatively safely produce h.265 content is to be one of these companies in one of the patent pools.
AV1 in contrast is supposed to be free of patents and open for everybody to use. Of course there could still be some patent being violated and there's no legal entity to fight for you if you get sued, but given the mess around h.265, this might still be the better option.
AV1 is backed by multiple soft- and hardware manufacturers, so between that, the free licensing, and the legal murkiness of h.265, this might yet take off.
I certainly hope so. It would be the first time in decades that the best media codec is also patent free and useable by everybody.
how are the optimized encoders coming along? last i remember it was 1000x slower to encode than typical.
Also there's rav1e which bodly claims to be the fastest (and safest) AV1 encoder, but it's still in early development so it probably doesn't make any sense in benchmarking it at this stage.
