The article seems much ado about nothing. It's not necessary to "major" in a subject to learn a lot about it. In the US (unlike the UK), undergraduates have the flexibility to take coursework in a broad range of disciplines. Nothing stops a journalism major from taking plenty of math and statistics and CS classes, assuming s/he can hack the work.

Should journalism programs require a course on "making sense of data and technology"? Yes, probably they should.
