A Mac book I'm reading recommends bailing on DVDs and just using hardrives for backup. The logic is that maybe down the road, macs wont be able to even hook up to optical drives.

I have a lot of redundant backups now with hardrives onsite and offsite, and even in the cloud as well, but still I think of DVDs and kind of a real tangible layer of backup, like a photographer having real film in addition to digital copies. Any opinions on this?

Would be nice to blow off burning those DVDs!
