SD content still outnumbers 1080p content by a huge factor too. So, apparently, we shouldn't embrace 1080p either?
The old & established "now" will always FAR outnumber the new & upcoming "future":
That's always the issue with this argument against progress because it's not already dominating the "now". The "now" only falls vs. the "future" when enough embrace that "future" to make it reach popularity dominance. If everyone accepts that they should wait until the "future" is dominant, it can't become dominant. And if you own an iPhone or a very new Mac or pay with Apple Pay or use an OS-X computer or have an Apple Watch or use Touch ID, etc, you're apparently not practicing what you appear to be trying to preach with this "wait until it dominates" argument.
- Isn't there many more iPhones that are not 6s in use than 6s? So we shouldn't embrace iPhone 6s until everyone else is on that bandwagon?
- Isn't there many more Macs not with Skylake, so we shouldn't embrace Macs with Skylake?
- Isn't there far, FAR more Windows-based computers in play than OS-X based computers? So we shouldn't embrace OS-X based computers?
- Isn't there many more iPhones that don't have Apple Pay capabilities than those that do? So we shouldn't embrace Apple Pay?
- Traditional watches vs. Apple watch?
- Touch ID?
- 3D Touch?
- 1080p at 60fps?
- iPad Pro?

Rubbish. Everything is broadcast in HD now and 99% of content is available in HD. Just go through Netflix and see how long it takes you to find something that isn't HD, and look on Amazon and try and find a movie that's not on Blu-Ray that you're not previously aware of.
And you are confusing two very different things here. 4K is a resolution, you can't compare it with hardware like TouchID. See if you have TouchID, you can experience 100% of what TouchID brings, but if you have a 4K TV you can only experience a small amount of 4K content. See the difference? Same goes for all of your other hardware examples. They are just not comparable in the slightest.
