Basically the only rule is: NOBODY (that much younger) will ever know how good or experienced you are. They just can't know. It's impossible for them to be in your shoes, but you CAN put yourself fairly easily in THEIR shoes and work from there...
Don't feel underused or misunderstood etc etc even if you blatantly are. You won't be able to change it anyway, just work with what you have, and use your remaining brain cells to do stuff they CAN'T do: for example learning the next big thing quicker than they will...
Ultimately, it's just tech. it comes, it goes... You've likely seem most of it before anyway...
Also, when you DO find the basket case of someone who is interacting with you like an ass and has no clue about your real value, remember that it's THESE GUYS failings that will ultimately keep you employed to make stuff work in the end :-)
