The Importance of Resource Constraints in Programming

A lot of it comes down to resource constraints, whether it's CPU or memory or network. How do I fit what I'm trying to do to work with that? Or maybe there's a future like with Ponylang or unison where I let's just imagine we have infinite resources. What would be ideal is, why can't the system figure out that for you? Right. So, Akka does this, where you send a message to an actor and that actor could be somewhere else on the network. It doesn't have to be in the same machine. But as a developer, you have to decide it's like local and remote EJBs.
