I'd never hire old engineers, they're stuck in their ways and insist on using SOAPJust as a nice case study...
I was "old" when SOAP got popular (late twenties early thirties). Most of my (age) peer group seemed to agree with me in that it seemed over complicated and messy. We were, of course, old stick-in-the-muds who couldn't adapt to the new technology :-)
It was the "young" developers who jumped on it more than anybody else that I saw - the everything-in-xml crowd.
Ten years on, of course, the "young" crowd are now seen as "old".
Plus ça change, plus c'est la même chose :-)
Ageism cuts both ways, and it's never an excuse for winning an argument or evaluating a person. You evaluate people on their merits or you pass over valuable people and pay the price for it.
Amen. Young and old both have stick-in-the-mud types. It's just that the young folk haven't had the time to demonstrate whether they are stick-in-the-mud types. You don't want to hire them whatever their age.
Using node.js (or whatever) doesn't make you cool, hip, and open to new ideas. I can guarantee that, if this forum is still around in ten years time, there will be somebody complaining about this old fker who wants to do everything in node.js :-)
