SmartTV are useless they are abandonware and they try to lock you into some ecosystem. I'm saying open functional standards. Motion is cheap pennies cheap and general useful outside of the TV. I dont want a stream of cam/mic going to apple/google I might no mind it going to my own gear, I do want vid conferencing and in home paging. Lux to get ambient lighting so internal or external controls can make adjustments. Network based controls allow for things like real time video overlay say a doorbell or baby monitor. Networking lets IR commands trickle back to other devices,
In many ways my voip desk phone has it nearly right but form factor wise it fits in on an office desk not a family room coffee table. Android powered TV's sound great but I dont seem the lasting 20 years like a TV should. So it's far better to keep the brains and the visible parts separate since the brains might get swapped out in the 3-7 years range while the TV lasts far longer than that.
