Heh. Truthfully, what I'm most excited about right now is being able to start a worker in less time than it takes to make an internet request. When you can do that you get magical autoscaling and it becomes just as cheap to run it in hundreds of places as one. As long has you have to invest ~100ms of CPU to get one of these VMs running I'm not sure it will have quite the same economics.
That would make me a little sad. I'm not excited about the idea that we figured out the ideal way for a program to be encapsulated in 1965 and it will never change.
