      I like this kind of skepticism of abstraction, and it reminds me of Bret's skepticism of interactivity in Magic Inkhttps://twitter.com/jonathoda/status/1032721095273664512 …

      Interesting, but don't you also have to blackbox things ("sweep the pile into a procedure") in electronics? e.g. the op-amp: You know how it works, but you don't look at its inner structure while using it as a component.

      Indeed! I think the difference is that programming consists of constantly churning out new blackboxed functions, whereas in electronics, you only occasionally make a black box yourself. So every op-amp is carefully designed, has a detailed spec sheet, application notes, etc.

          Do you see a problem with the "blackboxed functions all way down"? If so, what ways to decrease the number of abstractions do you know?

          electronics has all that spec only due to the fact that making a new function (chip) costs several hundred million dollars. this is not something electronics engineers cherish. they have always wished for the flexibility programming has, hence fpgas, uCs, etc.

          Names are one way to help answer the question ‘Given this bug, what function/module/program could have produced it?’ or ‘Where should this new bit of functionality be placed?’ Reminds me of https://youtu.be/DoA4Txr4GUs , which is about constraining programs (with types in this case).
