The television talk was a bit interesting. 4K's biggest issue is delivery. Having the TV means nothing if there's no pipeline to deliver content. RED's 4K server is too proprietary and SONY's is deprived of content/expensive and time consuming. None of these recent trends have caught on. 3DTVs were a bust and so were SmartTVs and for the similar reasons. No one wants to wear glasses to watch TV when they don't have to and SmartTV apps are slow, buggy, and unintuitive. No one uses them. Take a look.

Cable companies haven't even delivered on the promise of proper 1080p, 4K is mountains off. The networking pipeline isn't even there yet. People don't have the network speed to download 125GB+ (and that's a modest starting point) files in any reasonable type of timeframe.

The front end is ready for 4K, but the backend isn't. It's years behind. Games running in 4K... big fantasy. They barely run in 720p! How many people playing high end PC games are playing them at that kind of resolution on their PCs? Or even half that?

As a photographer/filmmaker, I dig the idea of 4K. I've shot my fair share of RED and it's definitely a clear upgrade in the cinema, but at home? TV industry is in shambles, companies will have a hard time selling people on a new TV.

Jeff is also smoking when it comes to Google Glass... that is way off. Expensive as hell too. That's like a generation away.
