This depends on whether one is entering a new field, amongst other things. And it depends on the field. Richard Feynman, for example, was innovating in many areas well into his 60s.
Newbies scare the shit of of oldies, seeing in them certain disrespect, ridicule, erasure. Even when newbies try their damnest to learn from the oldies the venerable farts can't bear to be used as stepping stones -- as if they never did that, and are not now robbing the newbies under guise of disdaining them.
There's a difference between newbies when a field is new and newbies when a field is old. When the Cypherpunks list started, many of us/them were newbies, regardless of our clock ages. (I was 40 in 1992, thus either disputing or reinforcing your "30-35" point, depending on your outlook.) Some newbies to our list have contributed important ideas. I remember when Lucky Green first started appearing, circa 1994-5. He went from having little background to being one of our most important essayists and actual crypto company contributors. And there's David Molnar, a student at Princeton when he arrived. It's true that I've seen nothing but "Look at me, I'm such a smart grad student!" comments from some of our recent newbies. And comments from lawyer newbies and law student newbies.
Meanwhile the Net geezers are agoing sclerotic heading boards and advisory panels, doing nothing challenging, burnishing each others' reputations, fencing what they thieve from students and prowling the Net for easy pickings.
True for some, not for others. I mentioned Feynman. John von Neumann was another. Many examples of people contributing more or less continuously into late life. The "move into management" is common in all industries, all institutions, so many of them end up sitting on panels and boards, attending special events, and genearlly being distracted from the singlemindedness they could have in their 20s. One of my long-term programming heroes is Dan Ingalls, the guy who invented BitBlt (for windowing systems) and did most of the actual development of Smalltalk. He's still in the thick of things and is contributing mightily. I recently had a chance to spend a few days with him and with other pioneers (Don Knuth, Gordon Bell, John McCarthy, etc.) and they are still doing creative things. Admittedly, for fundamental ontological reasons, the things that made their careers when they were young ("history gets written by the winners") were more earth-shaking than the things they are now doing. I say "ontological" because this is wired-into the structure of how we perceive the world--most people never make any substantial discoveries, a few make one discovery, and far fewer make more than one. For those who haven't made a significant contribution by age 30 or 35, they probably get shuffled off into jobs where future contributions are even less likely. So we tend to see precisely those people who contributed early on, sometimes more than once. --Tim May "The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others.
