Not really. There are a couple of developed nations that still have a high birth rate which shows that reduced fertility is not an automatic byproduct of developmnt. The current UN forecast is 11 billion in the early 22nd century. I think mother nature will have something to say about that.

I have several VMs on my system that each need at least a half TB to be useful (better a full TB.) A local cache of our SVN repo is again a couple 100 GB. Next, backups of my other systems, each a couple 100 GB at least. Next, a mirror of my server at work - nearly another TB or so. And a couple movie downloads that I haven't watched yet. Voila, over 5TB.

There was an article recently (can't remember where) that made the case that with slowing density increase the lifetime of HDDs has to increase because you're not going to replace them after two or three years anyway because the next generation is so much better. Much better MTBF is clearly possible - just look at HGST versus the rest in the Backblaze reports.

Yup, in large arrays the trend is to go beyond RAID6 - see e.g. NetApp's DDP. Too bad there's so little technical info available about it.

There's a significant effect though: The market for lower capacity HDDs has disappeared, and with it much of the volume so the HDD manufacturers have to make their margins at the higher end. 1TB HDDs are an endangered species now because you can get a 120GB SSD for the same price and many consumers don't need 1TB while they appreciate the performance of an SSD.
