Edited excerpt from the auto-generated transcript "it turns out the instruction set and the core of the CPU is not very important and and it's one of those big differentiating factors that people kind of fixate on but it really doesn't matter very much in the end. What matters is all the infrastructure around that instruction set and an x86 right now has all that infrastructure and it has it at a lot of different levels. ... I tend to look for is making if you want to make big progress in a specific area you need to figure out how to make lots of people care about that specific area and and that's the problem with small devices right now is it's really hard to find lots of people to care when most of the small devices you can buy tend to be very locked down for example and and I'd love to say that there's millions and millions of IOT devices that there should be tons of people caring about them but if all these IOT devices are actually hard to play with the only people who end up caring about these are inside companies and it's really hard to get a personal interest in small hardware when none of the small hardware really tends to encourage that kind of loving"
