Why don't you speak for yourself instead of inventing urban legends?
Both old timers and youngsters are individuals, with vast panoplies of
different attitudes and opinions. It is presumptuous and rude to make such
arrogant blanket characterizations.
There are plenty of old timers who like the bleeding edge, and plenty of
youngsters("young fogies") who are resistant to change.

notation question
I’m not sure I would use Java as a REXX alternative now we have Python. REXX is
very much legacy now. The old timers love it because it’s all they know but
push come to shove Python is much easier to learn then Java with all the OO
cruft.
