Your point makes good sense to me. In 1978, a system in which a low-level
integer was represented as an object with behavior would have been perceived
as a rediculously wasteful idea. And can you imagine someone seriously
suggesting something so wasteful as automatic memory management?

So if the "same" system was being designed today, it might very well include
new concepts that today are perceived as wasteful. Some of those concepts
might turn out to be very good thing once we get used to them.
