@atomicpoet On the creation vs. destruction rates: Total Internet data is still growing AFAIU.

The doubling rate has been about 18 months to 2 years, for decades now (and pre-dating both the Web and Internet).

So unless half of all data is lost within 18--24 months, no, the total would still be growing.

Though average lifespan is likely low. Internet Archive's metric is that the typical webpage on last 50 days until deleted or changed.
