If you're making the argument that knowledge has a shelf life and so you're always paying to update that knowledge, I urge you to consider if those payments are onetime or recurring.

It also seems you are overindexing on current, volatile events. Unless you're in Quantum space, Newton's laws haven't changed in a while. Sorting algorithms still function the same as does the x86 instruction set or how the human body reacts to ibuprofen.

Did I get your point, or am I missing something?
