Another way to see it: How would the original Smalltalk be designed if they would have had 4GB RAM in 1978?

What fascinates me still is that Smalltalk used the existing resources (even building their own machines) to an
extreme, while today we are obsessed to find reasons why we can not do anything that makes the system 
slower or use more memory than yesterday. And that even with resources growing every year…

This is why we e.g. now have a meta object describing every instance variable in Pharo. I am sure there are people
who will see these ~7000 objects as pure waste… while I would say that we have already *now* the resources to be
even more radical.
