LLM Usage is Exhausting LLM Usage is Exhausting

It seems we’re all finding how exhausting this new LLM world can be.

Quoting Margaret Storey on cognitive debt Cognitive debt, a term gaining tractionrecently, instead communicates the notion that the debt compounded from going fast lives in the brains of the developers and affects their lived experiences and ...

Really like the term β€œCognitive debt” from Margaret Storey.

Ditto. It’s like a of burst of productivity, but then I start to feel burned out - because even though I’m not coding, I’m still thinking so much about what/how to build that, review the code, test, etc. But I do this in a very compressed period of time and I get tired quickly.

Bilbo looking at his phone top

on bottom is ChatGPT

After all, why not? Why shouldn't I keep it?

You're absolutely right β€” you found it, it's been with you a long while, and it's only natural to feel fond of something that's served you so well, especially when someone like Gandalf suddenly seems to want it for himself.

I’ve seen Claude Code do similar things recently. When debugging a Django app, it would write a small Python script to inspect specific values of a model/view. It’s hit and miss, but it’s pretty ingenious.

Locast - Wikipedia

We used to have en.wikipedia.org/wiki/Locast, but then the broadcast companies sued it and it was forced to shut down.

First thought that crossed my mind. I imagine they got a boat load of money to come back, but you kinda make that decision before you move somewhere else. If you do so after, it’s because the new place is something so bad, you want to just quit immediately.

On the issue released on July 5, they attributed your work. Is this different than what you originally posted about?

Yeah, they always do this. They likely already knew that it wasn’t great. This is what betas are for. Not everything is polished and ready for public release. The only drawback is all the redundant feedback that was sent for this, which could have been used for something else.

I think for Florida, the insurance is extremely expensive due to the hurricanes, so a lot of folk can’t afford it anymore and just have to sell. Not sure about Texas.

Context engineering The term context engineering has recently started to gain traction as a better alternative to prompt engineering. I like it. I think this one may have sticking power. Here's an …

I think "context engineering" is going to stick - unlike "prompt engineering" it has an inferred definition that's much closer to the intended meaning, which is to carefully and skillfully construct the right context to get great results from LLMs simonwillison.net/2025/Jun/27/...

I still remember how confused I was about Twisted reactors and deferreds (first time learning about event loops). Then it clicked and I thought I could use them for everything. Until I realized I was in deferred and callback hell lol

Will Larson’s idea about advantage of authors in the age of LLMs Will has an interesting idea about how authors can still thrive in the age of LLMs.

Could this be the future of publishing?

> the evidence leans toward the post being real but removed, consistent with Musk's pattern of deleting controversial posts.

Something about the AI noticing that pattern is funny.

Watching this #UCLFinal and the last 2 minutes of the Barca-Inter come to mind. This would have been a much more entertaining final with some Barca Flickball (biased take).

I’m about 15hrs into it, and I love it. But I’m debating if I have the willpower to continue lol I have so many notes about every room and puzzle and every little thing, but every time someone online talks about it, I realize that there’s puzzles within the puzzles that I haven’t even noticed lol

I noticed that today and I thought I was hallucinating. I didn’t even considered trying it out. I just noped out of the console so fast.
