  As AI assistants become more agentic and take real actions, competitive advantage shifts toward platforms with deeper personal-data access.

  Their words

  But as workflows move more agentic - i.e. you want to use AI to take more actual actions - the advantage quickly shifts towards Meta.

  Educational methods should be validated by measurable research, not by how satisfying they feel to students and teachers.

  Their words

  The deeper lesson is that education has to be research-based and proven to work measurably, not just based on positive emotions or customer satisfaction.

  If you are not willing to try hard, do things yourself and dig deeper, you should know what you are getting yourself into before betting a career on tech.

  Their words

  The only reason I suggested that even in the title was that I think if you have an attitude of like you don't want to try hard, or you don't like you don't want to do things yourself, and you don't want to to dig deeper into things, like you need to do that. You need to do certain things. And if you're not willing to do that, I think you should know like what you're getting yourself into

  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.

  Locality 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 words

  but 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?

  A deeper coffee bed reduces astringency by trapping long molecules on particle surfaces, not by pore-size filtration.

  Their words

  the coffee bed would act on these molecules by filtering them out a bit like oxygen adsorbers keep oxygen in; it just provides a gigantic maze of free surface area for them to stick on, and hopefully the microscopic fluid velocity is gentle enough to not drag them along.

That frees up designer time to go explore more deeply the stuff they need to go into and it allows anyone to kind of add to that first conversation of where should we go and look further and wider and broader at the option space.

  Principles of the SPIN Model Checker

  Their words

  This book gave me both insight and a deeper curiosity about the subject. This book introduces the SPIN model checker and exposes the reader to the nuances of verifying programs using SPIN. A nice feature of the book is how it explains concepts using thoughtfully developed, freely available tools (such as jSpin) that the author created for pedagogical purposes. It's a demanding book, but the content was interesting. The book presents details about concurrency, temporal logic, non-determinism, advanced SPIN topics, and even case studies. I've already written a few blog posts about the topics I explored while reading this book, and I plan to write more. Overall, it's a good book. I'm sure I'll revisit the latter half again.

  Curiosity is the thing AI has not cracked: a model can research a question thoroughly, but it cannot decide which question is worth asking.

  Their words

  What makes humans special though, is our curiosity. Even if AI’s cracked this, it’s us still asking them to go explore something. And one thing that I feel like AI’s haven’t cracked yet, is being naturally curious and coming up with interesting questions to understand the world and going and digging deeper about them.
