So I listened to most of it. I don't really care whether OEM's profit or how, I want to know why regular people would have any interest in this at all.

He's changing the original plan as stated on their website. Their website says in big bold words:

"We've developed a chip for embedded bitcoin mining."

But this guy is talking about distributed apps - eg turing complete computation. Those are two different and mutually exclusive things. So I don't know who's correct here.

Let's say the audio guy is correct and they're embedding distributed app computation into all your devices. The guy says "oh you'll get *slightly* higher priority for stuff because your device spent energy on someone else's computation". This still makes no sense. If I want the 1 cent of electricity I burned to get me slightly higher chance of getting a parking space, why can't I just spend money directly?

He still doesn't address why it's beneficial for devices to sell their computing power, breaking even or at a loss, vs just using money that the device's owner earned, for example, from their job.
