No, COBOL is dead
A quick search through my usual job ads website reveals exactly three jobs which want COBOL skills; two of which only require the ability to read it, not to write it. The same site turns up approx. 1,200 jobs each for Java, C#, and Javascript.
Besides, for a new starter today, the correct question is "Will my COBOL skills still be in demand when I'm 60?"; to which the answer is emphatically no.
