DRM: More Bad News (super short post)

As I was browsing Wikipedia for fillable info gaps, I came across this nugget in the DRM entry:

"The use of DRM may also be a barrier to future historians, since technologies designed to permit data to be read only on particular machines may well make future data recovery impossible - see Digital Revolution. This argument connects the issue of DRM with that of asset management and archive technology."

It's a consequence I hadn't thought of; and one I find especially disheartening...
