Those 64x and 16x are just worse case scenario a bit exaggerated figures.
In 80 when MPEG-1 (and later 2) was born every 2 - 3 years CPU computational power was almost doubled, now we observe severe stagnation on this - rarely new CPU's are providing more than 20% processing gain...

We are slowly romping up against physical limits of chip production, and codec development is doing pretty much the same. Many of the changes are now an attempt at trying to discern an improvement or if its just noise due to the huge amounts of coding tools and their tiny contribution. At some stage it simply won't be worth upgrading codecs due to insane encode/development costs.
The JET folks really need to sort out their licensing mess though since AV1 can encode similar quality when compared to HEVC at 75% of the bitrate. Granted, AV1 seems a bit rushed but as long as most of the nagging issues from VP9 are fixed more people will hop onto it and stay if patent costs keep increasing with the h.26x codecs.
