No, they'll only become the new norm if the majority of people buy them. And they cost more, because internet-enabled components aren't free. And most people really don't see the value in an internet-connected light bulb. Does it emit more light? No? Then why would I pay more for it? So if they have to sell the higher-cost BOM for the same price (because people see no reason to pay more), then where are the gargantuan profits?

So I really don't see internet-connected X taking over the market, no matter how much money companies could make if customers cooperated.
