IT industry is in a bubble since 10 years or so. To sustain its economy it needs to generate so called new technology that obsoletes in a few years. It is called progress. Our web pages in Perl became web apps powered by frameworks like rails, that became apps on mobile written in C. They are fundamentally the same. Just using more and more resources, more unstable, less secure.

That's the price to pay for not having an industry anymore and keeping people that took a 90k$ loans employed. Old programmers are a pain: they have knowledge. Sack them all.
