“A visual designer turned out to be one of our best prototypers. An animator turned out to be one of our best prototypers. And what it seems like is these people are like great directors. They have huge context. They can describe all of the things. They are vulnerable and they try things without like worry of failing.” — Blair Metcalf, Lenny's Newsletter

“What I've seen in basically every single time I've seen somebody with a design partner is that you recruit a design partner who quote unquote buys into your vision for the product and they give a bunch of feedback and never buy from you. They never buy. And you realize that all of their feedback was just like them playing Steve Jobs… The people who actually have something really important they're trying to get done, they don't want to be a design partner. They just want that thing done.” — Rob Snyder, Lenny's Newsletter

“TLDR is that it just used the boring tools that are already on our computers. FFmpeg, Whisper, Python. Like it didn't upload the video anywhere… And then not only that, but it's listening and goes, oh, I just heard you say, cut that out. And then it also was like, you repeated this a couple of times. And I took the one that was the best cadence.” — Brooke Lacey, Lenny's Newsletter

“Predicting the next character in a dialogue requires behaving like the character in the dialogue would. And so, in that sense, part of their training, I think, can best be thought as training an actor, where it's like, you know, it's reading some play and it has to play all sides because it's predicting all the words.” — Emmanuel Ameisen, Lenny's Newsletter

“One of the early projects I did at Anthropic is I learned SQL, a programming language, and it took me years to master. And then as a little side project, I got Claude to learn SQL and it was better than me at it. And I'll never be better than Claude at SQL ever again.” — Emmanuel Ameisen, Lenny's Newsletter

“I find that the more you look inside, the less certain you are about how they work. And then oftentimes people that will confidently say like, ah, language models are just X or just Y are the people that actually haven't spent a while looking inside.” — Emmanuel Ameisen, Lenny's Newsletter

“I also think that a lot of times these chain of thought reasoning elements in the UI are there as a band-aid for latency, which is, it feels very frustrating as a user to sit and wonder, is my agent working on something and is it making progress or is it just stuck?” — Claire Vo, Lenny's Newsletter

“I got a text actually from my mom this morning… She said that she has apologized to her Muse for making him work so hard and thanked him for all that he's done for her, which I found really gratifying because I have been working in software for a long time and I don't think my mom has ever used a thing that I've made.” — Alex Cornell, Lenny's Newsletter

“We'll hear sometimes people talk about, what's someone's learning rate? Do they have a growth mindset? I'm actually looking a lot right now for people, what's their unlearning rate? How fast can they learn something and then walk away from it?” — Josh Woodward, Lenny's Newsletter

“If you just look at the data, a large company who starts a lab, the lab is usually ineffective and fizzles out after about three to four years. Or it may have duration, but the company can never commercialize the things coming out of the lab. And so you get things like someone comes by and sees the future, and then they do it as a separate company.” — Josh Woodward, Lenny's Newsletter

“I myself even get fatigued with the model picker and the reasoning efforts and whether to use multi-agent or ultra or what it even does. And you kind of need a PhD in model pickers.” — Tibo Sottiaux, Lenny's Newsletter

“If you put too much friction in front of people, they're just going to do unsafe things because that's how humans are, right?” — Sharadh Krishnamurthy, Lenny's Newsletter
