Yeah; I never learned to solve rubicks cubes for exactly that reason - what’s the point of memorising a solved algorithm that only works on this one problem anyway? But plenty of algorithmic ideas are broadly applicable and useful. Eg, b-trees, bloom filters and priority queues have some wild uses across a host of problems. Those tools strike my fancy.
