I read the entire manifesto thinking the discourse about a code execution model would lead to a revelation that this is a model that can reduce bugs in code in realtime and make sure the code runs to the original spec or blueprint. Instead it turned out to be about a model that keeps on optimising code that can go faster and faster over time. That's very exciting in its own right, don't get me wrong, but I was really starting to hope this would be about creating code that breaks less etc.
Maybe it means both but perhaps the emphasis is on speed.
