Hey! I've got 40 years in this industry! Yes, some of the stuff I first worked on used oil instead of electricity... And I still use a modem almost daily - the software I support requires it. Modems are so lame and obsolete that if you paid for a meal at a restaurant other than a chain, the card terminal used a modem. If you paid with a card for some bling for your smartphone at a kiosk, it probably was a terminal that used a modem.
For at least 24 years I've been largely cashless, don't ask how I know that. I've gone from writing 1500 checks a year to 40. I've got emails from 1987, been participating in online forums since 1988, got DDOS'd off of one in 1989, and am a charter member of a dating site I joined before online dating was, well, dating.
My team's most productive, knowledgable, and insightful member is also our oldest. He doesn't just keep up with the changes in our company and industry, he anticipates them.
Me? I pass for 10 years younger than I am, but I'm not out of touch with social media etc. I have other priorities. But I suffer some of the same problems the 'younger gneration' does: My attention span can be very short, honed that way by too much surfing the Web and too many short responses (this was a problem before the Twitter...). I tend to not retain certain types of information, since I can get it in a moment or two.
I've considered my phone a web browser since at least 2002, though WAP wasn't much fun. Oh, I still use WAP, and my website has a WAP side I keep alive for my personal use. My current phone is actually faster than my current home desktop computer, and my 4G connection is virtually as fast as my cable connection. If these metrics make me part of the 'youth-oriented culture', fine. But a youth-oriented culture isn't anything new at all. The idea of that alone dates you into the same culture as most of us fall into - marketable.
And I hate being marketed to. Assuming you know what I'm interested in limits me more than anything else. Stop it, or I'll slap you in the face with a large trout.
I'm part of the young generation if mid-twenties counts. Cloud computing is good only if it's set up as a corporate intranet. The Microsoft cloud or any external cloud is something I am against from a security perspective.
Also, cloud computing = NO for home use. If MS were to make it so all my programs, files, and applications were on THEIR servers I would never use MS again.
Why? I don't want any of my personal files or information out there. It's the reason I post on the internet with a handle, and that handle account uses an alias for a name if given. I still keep a fire proof safe bolted to the floor(the good ones with hanging file folders) to keep tax return copies in, savings passbook, and reciepts from groceries/etc in(for comparing to the credit card activity.)
My computer is from 2006, and until a part breaks that can't be replaced(main board only supports PCI-E 1.0 and the manufacturer didn't release any firmware to add 2.0 support.) I can run TF2, L4D2, almost any Source Engine game, WoW up to 10 man raids, and some other games fine. It boots fast enough for me, is responsive enough, and loads MS Word 2007(an upgrade I made to get .docx suppport and won't again until they significantly change the file formats) really fast.
Social Networking sites are a pointless exercise to me. Oh look status updates. Those same friends have an IM client, but they all wonder why I don't talk much. I talk plenty, it's just I run out of things to say to them connected 24/7 instead of hanging out, watching movies, and having a dicussion then, or doing a LAN party and on a food break talking about the nights frags, epic frags, and stupid deaths. I actually talk much more IN PERSON. Online chats with friends sometimes bring more problems because you can't always read tone of voice, facial expression, or body language that can completely change the context of a sentence.
I have noticed a disturbing trend in terms of job searches. HR is under the impression you must know 50 million langues or programs instead of placing ads for the fundamentals; then not pushing you forward if you don't have them. A good, solid understanding of the concepts like OOD, UML, and other programming techniques is more important(as others have mentioned) because picking up a new language is easy.
