  1. Our readingLocality is what makes a language good for AI: if a single file states what it imports and what it offers, a model never has to hold the whole program at once.

    Their wordsbut but if you have good locality where you you clearly stating what you're importing and whatever and and you can analyze just a single source file and from that extract its protocol to the outside world without having to to know anything deeper. Do you do you know what I mean? I think those are important aspects just simply to reduce the size of the of the of the context window and also make it easier to summarize each module in a program, right?

    Their wordsAI today it's just starting to to become aware of you know the existence of of of language services and agents today like to use grep and awk and whatever you know to to find all the places where you reference a certain thing but it's not semantic search, right?

  5. Our readingProgrammers are turning into project managers of an army of junior agents, and the craft is moving from writing code to reviewing it and holding the architecture.

    AI and jobsmanagement

    Their wordsIn a sense, we're all turning into project managers, right? And and we can have an army of junior programmers called agents that will just spit out reams of code, but someone's got to have the big picture and review all of that. And so, increasingly our craft is going from one of writing the code to one of of reviewing the code and and building the architecture of the code and overseeing the work, if if you will.

  7. Our readingResponsibility for a program lies with the programmer and never with the AI — there is nobody else to hold to account.

    Their wordsAnd ultimately also, you know, the responsibility for a program does not lie with the AI. It lies with the programmer.
