Depends on what you mean by "on par" -- especially when the question seeks to compare and contrast Perl with two of the most over-hyped entities in the IT biz.

If your question is about the current and future capabilities of Perl, my crystal ball says "yes; Perl will compare very favorably with either of those fads.

OTOH, if your question is whether Perl's buzz will be on a par with that of Java and .NET, even the Ghost of Christmas Future declines to opine.

Being made of somewhat more substantive stuff than the airey Ghost, I would offer a WAG: Likely not, but given its competence and current uses, I rather expect those will a good handle on Perl will find satisfying and renumerative employment will continue to find employers -- those inclined to apply objective measures to their staff needs, and more concerned with the steak than the sizzle.
