How to get an "unfair" advantage vs AI? Build real human connections. I've tracked that the a podcast episode takes me 8-10 hours to produce. Why do I do it? Well, learnings. But the most important is the motivation it gives me! Interacting with someone who I admire === energy++

On top of that, smaller models are cheaper leading to a faster feedback loop.

Learned this the hard way! When working in dev mode, start by testing your prompts with smaller AI models. They fail quickly and often, which is exactly what you want. Larger models are so capable that they can mask mistakes, making debugging harder.
You can’t combat “burnout” or mental fatigue through rest only—you need wild curiosity, aggressive spiritual effort, and intellectual vagabonding.
Today I did a talk on MCP in front on 30+ devs. I love writing and hate speaking. So much energy goes into how you speak instead of what you say. When writing, you can edit and refine. When speaking, it’s all real-time. But being good at speaking will always gives you a huge edge
How to make your side gig the most efficient as possible: 1. have a baby 2. Get a 9-5 job 3. Fit the side gig in the time left. In the end, constraint inspires creativity. It forces you to get real very fast.
LLMs && Coding 1. English has a more complex syntax & vocabulary than JavaScript. If an LLM can write decent English, there is a high chance it is able to write JS as well. 2. With a code interpreter, an LLM can validate its own responses & regenerate. This is unique & essential.
💡 LLMs, with their natural language processing capabilities, will become the UI. For example, you won’t need to learn Excel’s clunky interface and functions. The embedded LLM will understand commands like: 'Give me the average of the top 50% of values from the salary column'.
One of the nice parts of `langchain` 1.0 is standard content blocks for reasoning, citations, multimodal stuff, etc Has been annoying to see providers implement slightly different variants of these, this should help make it easy to treat these in a standard way

“I’m an engineer. I know code. I just never learned AI.” That’s who I built my teaching for. In a new @AITinkerers interview with @jheitzeb, we discuss how to fill that gap w/o semesters of math and why I teach by building GPT-2 in a Spreadsheet. youtube.com/watch?v=xUQMg3…

👥 I think the only truly long lasting moat is doing things that don’t scale. Showing up in person. Building genuine human connections one by one.

C. Newport and @dhh are right! I often find myself having 2 different discussions in MS Teams while attending a meeting on a 3rd topic. In the modern workplace, we’re battling to find space for deep work and flow. And we need them, not just to be productive, but alos to be happy!
