I happen to be living a little in both `worlds'. On the academic
part, I love and value other things than being arrogant.

I believe many people, including me, still love the APL character
set. It was (is) charming, in a way. Moving to ascii was a
compromise, and although the J operators were no less
thoughtfully designed (by the same person -- KEI), they are
probably harder to read. In the presence of a more
comprehensive character set, such as a widely accepted and
universally supported Unicode, the shift to ascii would probably
not take place. Btw, the APL character set is now really
present in Unicode, so nothing is lost yet. :)

The syntax of J and K is almost that simple as well.
No precedence levels, no left/right associativity.

I didn't know of this language -- thanks for the link.
Let us hope they did not create another monster like
`everything needs a class', `you should public-static-void-main
before you do anything', `you need class instances of three
different classes in order to read a line' etc.
Although, `really complicated syntactic precedence rules'
already sounds discouraging. :)
