It is not that hard to retrain if you don't think in a box. Many people just can't let old ideas go. The idea that you can't teach a old dog new tricks is garbage. Even with the so called world view shift lots of companies and projects don't bother with OO.
Oh, I think I can keep up. The difficult part is proving it. Even if I study on my own, if my resume doesn't show that I've attained new skills I may not get a chance to prove it.
Not that I'm that worried, I've always known this.
"Bark, bark!" went the old dog ...
You give me hope, youngling ...
