Well, I don't know that I agree with the 'disappear' notion. There's a finite amount of bandwidth available in given area. You're never going to be free of potential conflicts and degradation. Especially not when the trend is toward even higher bandwidth demands. Whereas you have a nearly unlimited potential for clear delivery with a wired connection. So anyone assuming wireless is going to work, let alone stay working is perhaps ill-advised.
It's always possible to go extra steps with a wireless setup to guard against problems. Like bringing additional access points into play or using different channels and/or signal strengths. But it only makes sense to weigh what might only be stop-gap measures for wireless against the known guaranteed results to be had from a hard wired connection.
I've no dog in the race one way or the other, just years of experience with proven success with using wired connections whenever possible, and wireless only in truly necessary situations like a portable device (tablets, casual use laptops, etc). A box already connected by wire to a TV and AC power is certainly not one that truly needs wireless. Bite the bullet and get a wired link setup and never look back. Heck, even a simple powerline bridge would be less worse.
