I feel that the most important knowledge that (some) baby boomers have is political organizing knowledge (i.e. how to build a movement, solidarity-building, union organizing). Luckily, this transfer of knowledge can only be accelerated by retirement (if the boomers choose to remain politically active).

Other than that, when I look at all that generation has accomplished/fucked-up, and I say meh. Better to loose the knowledge and build new structures.
