  1. 0:15 Having a good conference so far?
  2. 0:17 Are you having a good conference so far?
  3. 0:19 Good.
  4. 0:20 Wonderful.
  5. 0:22 I have a message for you that I hope will be a comforting message for folks who believe that their skill set is no longer worth anything in this new age, which is I believe that software fundamentals matter now more than they actually ever have.
  6. 0:40 I'm a teacher, and I've been recently teaching a course called Claude Code for Real Engineers.
  7. 0:47 Nice and provocative.
  8. 0:48 And in the process of kind of working on this course, I had to come up with a curriculum about AI coding, which is a bit of a nightmare because things are changing all the time, right?
  9. 1:00 AI is a whole new paradigm.
  10. 1:02 We need to chuck out all of the old rules, surely, so that we can bring in the new stuff.
  11. 1:08 And there's a kind of movement that has come up around this, which is the specs to code movement.
  12. 1:15 And the specs to code movement says that, OK, you can write a specification about how an application is supposed to work.
  13. 1:21 Then you can use AI to turn it into code.
  14. 1:23 If there's a problem with the application, you then go back to the spec.
  15. 1:27 You don't really look at the code.
  16. 1:28 You just change the spec.
  17. 1:29 You run the compiler again.
  18. 1:31 And you end up with more code.
  19. 1:34 Raise your hand if you've heard of that.
  20. 1:37 Keep your hand raised if you've tried it.
  21. 1:39 Okay, I've tried it too, you can put your hands down.
  22. 1:43 What I noticed was I would run it and I would try not to look at the code, but I would look at the code and I realized I would get code out first of all and then I would run it, I would get worse code.
  23. 1:54 And then I did it again, I got even worse code.
  24. 1:56 And I got it again, I kept running the compiler, kept running the compiler and I would just end up with garbage.
  25. 2:03 You know, raise your hand if that's happened to you.
  26. 2:06 Yes.
  27. 2:07 I don't think this works.
  28. 2:08 The idea that we can just ignore the code and just have the code let it manage itself is just sort of vibe coding by another name.
  29. 2:16 And I didn't believe that back then.
  30. 2:18 I thought, OK, how do I fix the compiler?
  31. 2:21 How do I make it so that it doesn't produce bad code each time or worse code?
  32. 2:25 And so I thought, okay, I need to explain to the LLM in English what a good code base looks like.
  33. 2:31 Let me dig out one of my old favorite books, which is A Philosophy of Software Design by John Ousterhout.
  34. 2:37 Go on Amazon, get it.
  35. 2:40 And he has a definition for what bad code looks like.
  36. 2:45 He calls it complex code.
  37. 2:46 Complexity is anything related to the structure of a software system that makes it hard to understand and modify the system.
  38. 2:53 So a bad code base is a code base that's hard to change.
  39. 2:57 If you can't change a code base without causing bugs, then it's a bad code base.
  40. 3:01 Good code bases are easy to change.
  41. 3:04 So I thought, ooh, that was good.
  42. 3:05 Let's try another book.
  43. 3:06 Let's try The Pragmatic Programmer.
  44. 3:08 Go on Amazon, get it.
  45. 3:10 they have a whole chapter on something called software entropy.
  46. 3:14 And this is exactly what I was seeing.
  47. 3:16 Entropy is the idea that things tend towards disaster and floating away from each other and collapse.
  48. 3:23 And this is exactly how most software systems behave too, is that every time you make a change to a code base, if you're only thinking about that change, not thinking about the design of the whole system, your code base is gonna get worse and worse and worse.
  49. 3:35 And that's what I was seeing.
  50. 3:37 everything inside the specs to code idea that you just run the compiler again and again was making worse code.
