If You Can Climb Up, You Can Climb Down
Mostly true, but the edge cases where this is untrue for adults are interesting:
Climbing up may damage the thing you’re climbing (rock, tree) and render it impossible to return by the same route
Steep and slippery surfaces can be more dangerous to hike down than to hike up, because gravity is in your favor for arresting uncontrolled upward motion but exacerbates uncontrolled downward motion
Without a spotter, we tend to have better line of sight to things above us than to things below
If fatigue or injury is incurred on the climb up, one’s physical abilities may not be sufficient for the climb down
It feels like a loss, yes, but a small loss, like a single building of architecture eroding into the sea.
It does not feel like a loss of the hope for more similar schools, to me, because it existed for how long and yet spawned how few spinoffs?
If it was going to change the world at scale by existing, it sounds like it had plenty of time to do that. Why didn’t it? Why wasn’t individual love and appreciation for it enough to coordinate efforts to create more such schools?
Certainly, for the few who would have been very very lucky and gotten in if it hadn’t ended the program, it’s a potential tragedy. But if the program wasn’t successfully lowering the luck threshhold required to benefit from its ideas… I don’t feel like that’s the same loss as if we were losing a program which demonstrated an ability to scale and spread.
