AV1 already wins handily as a codec, and the only thing keeping it from being adopted more broadly than is currently the case is lack of hardware decoders on older hardware. This problem naturally solves itself as old hardware gets replaced.

Even then, dav1d is a remarkable piece of software, and software decoding is pretty viable for AV1 thanks to it. Many places have already adopted AV1, and you should expect to keep seeing it get adopted as time goes on.
