Yup, tellies will die out because VR simply does everything better. And that's before you take into account the savings that he mentioned with regards to building, transporting and shelf space. Who in their right mind would want a telly when you can have a far superior viewing experience with VR..?
You'll probably find tellies costing the equivalent of 400 quid and VR headsets costing 30 quid each. A family of 4 and you're talking a saving of 280 quid. Who in their right mind would want to opt for a telly instead..? Paying more for an inferior service, paying for delivery etc.
The telly is going to be going the same way as the Dodo in 20-30 years.
