They're all wrong...
I find the 2009 Kryder prediction surprising, given that he must have been aware of the limits to PMR and the predicted costs of future technologies at the time.
As for the IDC data/storage growth projections, I'm sure they will turn out to be wildly wrong. The reality is that applications and data grow to use the available processor / storage capacity (until we run out of ideas for worthwhile new applications). If the rate at which storage becomes more affordable is slowing, then applications that would utilise larger amounts of storage will not be implemented.
Similarly the recent slow down in the advance of CPU processor speed has not resulted in a crisis of CPU power not keeping up with application demands. Developers write new applications or new features to utilise the available CPU power.
ergo YouTube will probably decide not to let users upload unlimited amounts of 4K or 8K videos that are full of duplicates, fake movies, people filming themselves mumbling on for hours about their dull opinions and not bothering to edit their footage at all.
