We millennials are all middle age.

There's roughly 4 to 5 generations alive at any point and the middle generation is going to be considered both old and young by the generations surrounding it.

Once Gen beta starts we'll be officially old.

Middle age != Middle generation.

I understand your point. But you're redefining widely accepted usage of these terms. Nobody would call a 30 year old "middle age."

You're right. 8 year olds would call you ancient and 80 year olds would call you a baby. Middle age is relative and unless you're over 45 you don't admit to it, and then hold on to it for too long.
