How can I be so sure? I do believe I'm qualified to make that judgement.

Because one mining chip provides pitiful amounts of mining and a lot more consumes far too much power for a generic consumer device. Power consumption is a huge part of a consumer device. Many chips require ridiculous amounts of cooling and TVs and other consumer devices do not usually have any significant amount of cooling; a few heatsinks and maybe one small fan at most. The one chip pitiful amount is seriously not even worth a few satoshi of mining and there is no "generic way" to mine. All mining happens at pools and even at pools one chip won't provide enough to get a payout even once per year. Samsung isn't going to start running their own mining pools to allow people to earn dust amounts of mining that they can never actually redeem, nor will they waste effort and time developing their own chip for such a futile exercise. Samsung will happily press chips for other morons because that's what their chip foundry is designed to do. They don't care what crap designs they get given, they just have to press them at ever decreasing sizes for ever increasing costs to get their money.

Forget it, the equation doesn't work.

As someone pretty familiar with the economics of single-chip miners - yes, exactly. The cost of integrating one chip into something would profit the chip vendor, and the integrator (if he could sell it), but never the customer. The customer would only pay extra for that much mining if he's an idiot unaware of the economics of the situation, or just doesn't care about the economics of the situation.

Been saying that for years, and if anything, the economics keep getting worse with time.
