AI or Art?

Ilya Sutskever said in 2017, whilst building OpenAI:

Within the next three years, robotics should be completely solved, AI should solve a long-standing unproven theorem, programming competitions should be won consistently by AIs, and there should be convincing chatbots.

There was a viral YouTube video from 2014 called Humans Need Not Apply [1], which made a very strong argument that mass unemployment was right around the corner.

I actually think people from the past would be surprised at how slow AI has progressed in the end. Although the domains where it's turned out to be most effective - code, images, videos, music, etc. - would probably surprise them.

I take your point - no doubt I approached this in a very naive way.

That said, we did collaborate on it - at the very least I needed to learn his address before sending.

Neither of us have ever sent or received a package in Uganda. It was a learning experience for both of us.

~$200 doesn't go as far as you'd expect for good used laptop, even in Uganda. We did look into our options.

However, there's definitely a sunk cost aspect to the operation. After the first failure to send it through Australia Post, I became determined that Django was going to have that MacBook.

I have a feeling that a big risk of using AI all the time is that our own neurological capacity starts to dwindle.

Just as many people leading sedentary lifestyles have to make a deliberate effort to exercise, because inactivity is really bad for our bodies, I think we're going to realise that a similar process is necessary for our minds.

You really want to be spending a bit of time every day operating at your cognitive limits - trying to fully engage your System 2 - if you want to avoid brain atrophy. Coding used to kind of give you this exercise for free, but you can go really far with just your System 1 nowadays - literally get things done while scrolling Reddit.

I'm trying to allocate 30-60 minutes a day to doing something difficult, like writing code by hand for an unfamiliar problem or reading and summarising difficult papers without AI.

Yeah, not locked in with Obsidian.

I just use it as a Markdown viewer/editor, and it handles updating links across notes when a file is renamed. There are some handy conventions that Obsidian encourages, like Daily Notes, templates and linking across notes, enough to call it an Obsidian project, but yeah - it's just markdown. I don't even use the [[Wiki-links]] style that it uses by default.

I already had the hierarchy from years of maintaining the notes, but for new things I do collaborate with the model on how best to structure stuff and get it to refactor when needed.

I recently switched to Codex using my ChatGPT Plus subscription, so only $20 a month or so. Before that, using Opus 4.5/6 it was like $100-150.

Opus was by far the best at the job, but Codex with GPT 5.4 is decent.

Wow. This is a really cool idea. I am using Obsidian for family history, but I never thought to let people chat with it and update it via OpenClaw.

I still use it and find it helpful.

My OpenClaw instance uses an Obsidian project as its memory. Mainly, it's just my main day-to-day LLM that I access via WhatsApp, but instead of the memory being locked away with a specific vendor, it's stored in version control that I can read and edit. That reason alone makes it compelling to me. When a better LLM comes along, I can just switch, and my memory and system prompts come with it.

However, I also use it for calorie/weight/workout tracking, to-do lists (bill, birthday, event reminders), and to support my various life admin tasks. I don't give it access to much at all, except a few skills that give it read-only access to some data.

Hasn't given me a 10x productivity boost or anything. It's just handy.

I wrote an article on it, if anyone is interested: https://notesbylex.com/openclaw-the-missing-piece-for-obsidi...

I had always assumed that all of them shared the pseudonym of Satoshi, along with Nick Szabo.

Back wrote the white paper with input from Hal and Nick Szabo. Sassaman did the coding work on the client. Sassaman had the keys to the Satoshi wallet, hence it never moving since his passing.

Since Satoshi is a collective, it means that each of them individually can claim, without lying, that they're not Satoshi.

That's my uninformed guess.

Grok 4.20 Beta 5 months ago

The thread is just a link to Grok. There's no information about the model or anything to discuss. If they release some information about it, maybe a benchmark or two, I'm sure there'll be more of a conversation.

It has hit the mainstream imo. Most people are content with the amount of music already available.

It's not complicated at all. You don't "manage agents". You just type your prompt into an terminal application that can update files, read your docs and run your tests.

As with every new tech there's a hell of a lot of noise (plugins, skills, hooks, MCP, LSP - to quote Kaparthy) but most of it can just be disregarded. No one is "behind" - it's all very easy to use.

Interesting to see so few comments about this.

This is the start of the end of generative AI music.

Without the entire music catalog, they are just not going to be able get the diversity and quality of outputs they once had, and the labels are always going to have their hands out wanting more.

Udio and Suno have demonstrated that okay-quality new music can be created by training on vast collections of pirated music, and, as expected, the music labels shut them down.

I find it useful. A nice little tool in the toolkit: saves a bunch of typing, helps to over come inertia, helps me find things in unfamiliar parts of the codebase, amongst other things.

But for it to be useful, you have to already know what you're doing. You need to tell it where to look. Review what it does carefully. Also, sometimes I find particular hairy bits of code need to be written completely by hand, so I can fully internalise the problem. Only once I've internalised hard parts of codebase can I effectively guide CC. Plus there's so many other things in my day-to-day where next token predictors are just not useful.

In short, its useful but no one's losing a job because it exists. Also, the idea of having non-experts manage software systems at any moderate and above level of complexity is still laughable.
