The term is not "inconsistency" but "variety": different situations 
require different list like structures for efficient handling.  You make 
it sound like having only one data structure for an abstract concept 
would be a value in itself.  That might be true in mathematics but not 
in a software developer's real life(TM) because even though some 
requirements are identical (ordered storage) many others might not (e.g. 
varying size vs. fixed size).

Oh, Integer can serve other purposes as well: by having an object 
reference you can encode more information, namely "value absent" and 
"specific int value X".  The argument that Java is somehow deficient 
because it mixes primitive types with object types is not new.  The fact 
has some drawbacks (some of which were fixed with autoboxing) but it 
also has advantages.

I don't see an increased risk here.  Strong typing prevents misuse.  And 
the term used for Ruby & Co. is "dynamic typing" not "lazy typing", 
while also these languages have strong typing (i.e. every object has a 
specific type all the time).  It's just that variables and expressions 
do not have a type which can be statically determined.

I would not call these languages more consistent.  It's just a different 
concept and mindset - dynamic vs. static typing.

Kind regards
