You simply mention a bunch of words.

pre-packed examples of “services”... ;-)

As I understand you, your TV hub concept is similar to the smart TV concept. Where is the evidence that people even want notifications on their TVs? Video and audio calls on the TV fine, but text messages? Are there really people interested in ecommerce on the TV?

I tell you in other terms:

In few years that “dumb” interactive televisions will substitute personal computing at all for mainstream home/family contexts.

An over-simplified interaction (with TVbots) will substitute nowadays “too complex” web browsing with PCs. That’s the idiocracy-computing (joking).

Apple couldn’t seem to find them with the Apple TV. They really tried to sell the idea of home shopping! WeChat is popular exclusively on mobile devices, so I don’t see the point.

Apple: I agree with Chris Messina’s points here:
WeChat: I mentioned the Chinese corporation as example of a mainframe grid.

People don’t use technology for technology’s sake, they use technology to accomplish a job to be done. So whether a Sam-like AI is adopted by the mainstream depends on how it would improve their lives — which primarily comes down to good design.

Mhhh… Is not at all question of “good” design. Almost now Amazon is focused on accomplish the “job done” you mention and I now leave to your to guess what’s the final company goal.

In any case: how exactly does the Echo Show translate into your vision of a family-centric TV hub? It’s got a 7" screen.

Size doesn’t matter. 
Echo Show is just a quick prototype to prove the concept.
It’s comparable to what Echo dot is now for Echo.

Hi assume that the final asset will be probably modeled with an in-home satellite mesh with a big television as a central hub (let’s call Echo Main TV), with minor Echo Show satellites :)

The Echo is a fantastic device, but the Echo Show has to prove itself first.
Echo Show is just Echo next step of Amazon strategy & vision.

My two cents :)
