I was told when I majored in CS in year 2000 that "in 20 years Java will be the only language" and also "it will impossible for an American to get a job as they will be hiring all of their programmers from India"
But when I want to university to study CS in 2007 it was just a marginalia.
Some profs would use it for examples, but until Android gave it a second spring in 2010, we mostly used C/C++ and PHP.
