You are very right with this comment. We are creating a digital Dark Age. Just try to read WP4.2 files, old digital photo's, early digital recordings etc. Even if you have the equipement for it, decoding the format is near impossible unless it is a publicly documented format (on real paper..)
And if you think it is bad with recordings of 25 years ago, just imaging what happens when you throw today's desire to keep everything for 'the rightful owner' with DRM in the mix.
