If qbits double every year, we’re at 20 million in 15 years. Changing crypto takes a very long time on some systems. If we’re at ~20000 in 5 years, we better have usable post quantum in place to start mitigations.

But I’m not convinced yet, we’ll have those numbers then. Especially error free qbits…

For how long though? How do you know these are real people?

Soo they added webp and AV1, which aren’t that much better then old jpeg, especially with the modern jpeg encoder JpegLi. But JpegXL is out of the question.

Those examples all have a good reason that does not apply here. Browsers already support multiple formats and added a few in the last decade.
