In my capacity as possibly the second or third oldest character still actively doing protocol development work in the IETF, I defer to Randy (who is older :-)). But let me suggest that the problem isn't numbers or ratios. It is what we do about leadership development, including how we use whatever expertise and perspective the geriatric contingent represents. At the risk of repeating something about which various ADs and others have gotten an earful, unless there are very special and unusual circumstances [Note 1], it is unwise to, e.g., have us chair a WG or assume many other leadership positions. It is easy to say "So-and-so should chair this WG because, based on a dozen before it, she knows how to do that". Instead, it is better to find someone more junior and, if appropriate, appoint the more senior people to advisory and support roles. We probably don't follow that principle often enough. Perhaps there are properties of our procedures and how we designate roles that discourage it. If so, we should fix that. As long as a significant number of newcomers are appearing, signs of an aging leadership are almost certainly a leadership development problem (which could include insufficient advancement of people with several years, but not several decades, or experience) and not merely an aging population problem at the top. Just my opinion while striking my white beard (which I'd probably be doing loudly at the microphone if this came up in a plenary). john [Note 1} I believe that my current co-chair role in EAI and Vint Cerf's recent role in IDNABIS were, indeed, special circumstances. And I'm looking forward to completing EAI and dropping out of that role almost as much as I think Vint was looking forward to completing IDNABIS.
