We need to 'factorise/elaborate' "interesting" ; thus: 
Oberon is "interesting" in that:
* it is the Nth stage of a journey to simplify a block
 structured procedural language;
* strong typing, further reduces the programmer's 
  mental load, by delegating the checking to the computer
  [to the compiler].

Does A2 contain any similar 'universal principles' which 
contribute to economy of effort for maintaining and extending
itself?  Apparently unix was named as a spoof on its ancestor
[competitor], multics which was said to be a complex failure.
So if A2 can achieve <what is required> significantly more 
economically, why was it overlooked in the recent BIG mobile
device OS repositioning?  Eg. various options were considered
by google, before deciding on <linux based android>.

It would be interesting to read a side-by-side comparison
[perhaps tabulated] of *nix <-> A2 
Attribute1 achieved-by-X1   achieved-by-Y1
AttributeN achieved-by-XN  not-needed.

You can't overlook the forces of inertia re. socio-economic
factors. Eg. LEO is cost effective because it can ride on the
back of linux, which can ride on the back of x86 PCs.

But the electric power inefficient WinTel monopoly
seems to be being broken by the 'mobile' market. And the 
mobile-market is the inevitable Alvin-Toffler-3rd-wave element,
where the 2nd-wave regimentation in schools, offices, factories
via the clock is replaced by flexibility.

Is there any need now for masses of people to syncronise
their travel, to attend the professor's lecture?
