LotusNotes, FoxPro, Php, Perl-CGI programmers … had to branch out and take up new aggressive, colonizing technologies. Their massive T-investment (mostly GTD) in the old technologies has lost value.
Q: will I need to branch out of java till age 65@@
%%A: I don’t know.
In 2012 I thought I had to embrace the new technology of c# but now in 2019 I feel java dominance has grown, rather than eclipsed by c#
If I have to branch out to take up another technology, that colonizer will NOT be c++ or c#. I won’t speculate on other challengers.
