It seems to me that all of those things very much are abstractions. They are not the utmost level of abstraction, but they are abstractions!
(Actually "a contract," which at first I thought was the clearest win, I'm now not sure about. On reflection, it seems like a concretization, turning abstract ideas of trust and reliability into concrete conditions under which the contract has or has not been met.)
- astrobe_ 2y agoAll right, light is an abstraction, contracts are abstractions, 10 is an abstraction, time is an abstraction, and I am an abstraction too. The notion is so fuzzy that everything can be an abstraction in a certain way. The word "abstraction" is a black hole for thoughts. Stay away from it. For instance in this threads and in TFA, people made useful distinctions such as "generalization" or "indirection".
