Oh definitely, no argument here, I'm 100% ok with AV1 becoming the standard "video codec to rule them all", but I'm saying that in the short term, it's difficult to recommend AV1 or VP9 over h264 (at least for personal use). H264 encodes 10x faster, still gives reasonably decent compression, is supported by basically every consumer device [1] and browser out of the box, and very soon will have all the patents for it expired meaning that it will be truly royalty-free. x264 in particular is extremely nice in my experience, doing a lot to really squeeze out a lot of quality in a relatively small amount of space.

That said, AV1 is very obviously the future, and I'm perfectly happy with it taking over the market from h264, and I think that due to the bandwidth savings it's only a matter of time before all the major video services make it the default, especially as the speed of encoders increases to a useable level, which I'm sure it will soon enough.

[1] I know the most recent Raspberry Pi doesn't have a decoder chip for h264, but I think it's fast enough to do it in software.
