Your comment makes me feel really young! I'm younger than Wolfram Research but older than Mathematica.

Having just attended our 25 anniversary celebration in Illinois, it's clear there is an enthusiastic and long-lived community around Mathematica that is only going to grow.

With any luck, 2014 will be a "breakout" year in which the Wolfram Language that underlies Mathematica will start playing a more mainstream role in the software engineering industry.
