Dunno about consoles but PC has been all digital for years, possibly decades by now. Physical PC boxes are just an install disc with a code for Steam, Origin, Uplay, etc. Well, they used to be anyway. Haven't actually bought a physical box in 15 years or so. For all I know they might not even exist anymore.
IMHO digital isn't the problem. I like digital because I can put all my games on an external harddrive and they take up almost no physical space. As far as sales go they've been much better than in the olden days too. Of course you can't resell your games anymore but I don't care. I'd rather keep them anyway. The big problem however is DRM which make you reliant on someone else's server.
