This means that today's techies have to learn stuff pretty much for themselves, ironically making them tougher and better disciplined people.
One must admire the grit of these foreign grad students, too. Mastering technical subjects without any knowledge of or cognizance of the Western canon and languages from which they spring is mighty tough. Too gd many of them here, though/
that was problem in those fields 25 years ago. Some things never change. Teaching assistants. Ugh.
One of the reasons I enjoy being in tech. Constantly changing, yes I have to study to keep up, but I actually find that aspect enjoyable. Learning new things should be fun.
