How Long Until CDs/DVDs/Blu Rays and Other Physical Copies are Obsolete?

I was looking at my Blu Ray collection and I was just wondering. How long do you think until physical copies are obsolete or at least largely obsolete (similar to vinyl)?



I dont think that we're going to get a successor to Blu Ray. I think it will just become higher quality digital releases.



Laptops come without CD drives now. Tablets are big. Streaming music is really popular and so is buying CDs over Itunes, Google, etc.



Just curious to see what other think.
