  AI has lowered the barrier enough that non-technical people with strong ideas, taste, and cultural awareness can build successful businesses.

  Every action a person takes is the output of a reward-against-effort calculation the brain runs, and most of that calculation happens below awareness.

  Their words

  We were talking about reward versus effort. And essentially that's a very important way I think that we make a decision. Much of that could be subconscious.

  Making AI compute cheaper per token drives enough extra usage that total AI energy consumption rises rather than falls (a Jevons paradox effect).

  This is the Jevons paradox in action: making compute cheaper per token in turn tends to lead to greater levels of AI use.

  Top-down product leadership works when the leader is in the weeds; what people call micromanagement is a leader directing work without knowing ground truth.

  Their words

  Top-down works well if leadership is good enough to be in the weeds and be specifically correct. I think where it falls apart is where you don't actually know ground truth and then you attempt to manage people from above and that's where I think the term micromanagement comes from.

  Systems thinking is the most useful skill of the coming decade, because everything below the system level will be done agentically anyway.

  Their words

  one of the most important things is systems understanding. Systems awareness, system design, system organization. Um, but systems thinking. And the reason for that is because most of the low-level things that that has to be done are going to be done agentically anyways.

  Telling a patient "your feelings are valid" is not therapy: it is the mirror image of "get a grip", and it makes the therapist a judge of feelings instead of a companion in them.

  Psychotherapy

  Their words

  The phrase "your feelings are valid" does not invite curiosity or deeper self-understanding, which is the point of psychotherapy. It is the mirror image of "stop whining and get a grip." One sounds warm and one sounds harsh, but neither deepens self-awareness.

  Agentic code search has recall that falls as a codebase grows, so the agent does not find the code it needs -- and which search tool you give it barely matters.

  Their words

  You can give it a Bash tool so it can ripgrep its way through the codebase. You can give it some queryable codebase index, an LSP server, a vector database. In the end it doesn't matter much. The bigger the codebase, the lower the recall. Low recall means that your agent will, in fact, not find all the code it needs to do a good job.

  Ask gamers what kind of player they are and they describe the player they wish they were, so a designer has to watch what people do rather than believe what they say.

  Their words

  We all, to some degree, lack the self-awareness of how we tick. So we’re all different types of gamers, but if you ask me to describe the type of gamer I am, I might actually be giving more of a picture of the type of gamer I wish I was or the type of gamer I want you to think I am versus the type of gamer I actually am.

And so what you find is that a lot of things that typically get categorized as a bad habit, eating too many donuts or smoking a cigarette or something like that feels good in the moment, but it creates some kind of cost or consequence in the future.

  Their words

  the tool is used when you are overwhelmed with too many options. You've said yes to too many things, and you need to raise the bar all the way up so that almost everything doesn't pass the bar. It's a tool for a certain situation so I rarely use it. I would not call it a approach to life that everyone should use all the time.
