Mechanical Engineer who quit his job to build an AI startup. I have an idea to make generative CAD design truly generative. We'll see how it goes. Lots to do. Lots to learn.

I still have an X account, but I've tuned it to only show stuff about engineering, manufacturing and AI. All the political stuff is gone; if something creeps in I kill it. Bsky is where I go to relax and enjoy discussions outside the engineering space.

”60% of people are below average creativity” “LLMs score a .25 on a 0 to 1 scale” A significant number of people reading this will miss the joke. Here’s the pre-print in all its glory. It’s a masterclass. osf.io/preprints/ps...

I think they were gently reminded by Disney of their contractual obligation. After Disney was gently reminded of similar obligations by Jimmy Kimmel.

Some thoughts on the usefulness of LLMs: We are used to very narrow domain computers being perfectly correct. We not at all used to very wide-domain computers which approximate correctness. It's the difference between looking up information in a textbook and asking your friend for help on homework

Basically, LLMs "know" things because we know things and it's trained on our writing which is embedded with our knowledge. We are used to computers which are absolutely accurate in very narrow domains. LLMs are approximately accurate in very wide domains. It's a whole new thing.

This is basically how research goes though, correct? For knowledge outside your own expertise, you are typically consulting sources and taking the consensus. Wikipedia is simply random people writing things which make sense to them. It's still valuable as an approximate source knowledge.

Because Republicans are the ones causing it. They want this. We don’t need accounting of “blame”. We all know who to blame. We need accounting for action. If our reps don’t act as a counterbalance, then the only other opposition is the street. Or we just lie back and let it happen.

Everyone shout it out loud. We don't have Kings in America! "king" Trump is anti-American. Why do Republicans even support this? Wouldn't it be hilarious if "king" Trump has his parade and nobody came? Or better yet, how about a website to charge MAGA $30 each to attend for free?

Trump as Pope really highlights the difference between modern conservative and progressive. Conservatives are interested primarily in the person involved. Progressives are interested primarily with the ideas involved. Trump as pope is the same as Trump with a muscular body. A form of idolatry.

Yes, this. The model isn't "reasoning" in any sense of the common use of the word. It's basically an internalized chain-of-thought to get a better quality response by dragging out inference.

Trump has done something no other President has done in a very long time. He’s pushing the US towards a socialistic planned economy. Tariffs calculated based on trade imbalances are a super far left move.

Last time tariffs like this happened, WWII ended the economic doom by converting a lot of flesh/blood to the manufacture and use of weapons.

Democratic supporters can't control Trump, but they might be able to influence the Democratic party. This criticism might actually help give cover to the Democratic politicians to be the opposition. Politicians get their power from their constituencies.

One might argue “native” does have some specialness, since US citizens are bound wholly by US law, whereas foreign owners of corporations have a split obligation. Particularly when it comes to China and Chinese law. This is certainly taken into account.

Brian Ratliff @brierrat.bsky.social · 11/12/2024
okay, that makes sense. But this doesn’t really have bearing on the discussion, does it? The courts define the constitutional protections in detail via their rulings. They aren’t some separate interpreting organization aside the constitution. If the SCOTUS passes, the interpretation stands

Brian Ratliff @brierrat.bsky.social · 11/12/2024
I think you are trying to make up some sort of broad principle and then argue against it. Specifics are the only thing that matter in this. China/TikTok/national security balanced against free speech are the specifics. Courts are the ones doing the balancing. Not sure your point anymore.

Brian Ratliff @brierrat.bsky.social · 11/12/2024
2 points: 1) “It’s not American” can be a meaningful constitutional argument, because the 1A protections are not absolute. Under conditions. 2) “it’s Chinese”, and the associated way China deals with its corporations, is absolutely a balancing factor for 1A protections.

Back when Wikipedia started, it wasn’t like that. I assume ChatGPT will get that way as well. With wiki, until that happened, you had to take it with more than a good dose of salt. My point is we’ve been here before. We dealt with it. We’ll deal with it again.

Brian Ratliff @brierrat.bsky.social · 11/12/2024
Wiki’s not a source, but it’s good for casual knowledge. ChatGPT too. Working knowledge has always required first sources. Here’s the kicker though. Most knowledge doesn’t need to be working knowledge. 85% correct is good enough. ChatGPT and wiki both are about that: 85% correct.

Back when I was going to school, the all-knowing lying machine was Wikipedia. So, take two, I guess. You can take the same text and replace “ChatGPT” with “Wikipedia” and you’d have the exact same conversation from 20 years ago. Now Wikipedia is god and LLMs are the liars.

I was dreading figuring out how to put a bunch of files in a .json alpaca format for training a homebrew LLM (I am not a programmer). Claude gives me python code with a prompt and half an hour later (including time for me to understand said code) and I have a function. Stupid simple.

LLMs don't have direct experiences, but neither do people, on the vast majority of information we hold in our heads.

Brian Ratliff @brierrat.bsky.social · 06/12/2024
The counterpoint is, this is essentially what we do as people as well. Our knowledge comes in two types. One is direct experience. But the bit about a country south of Rwanda is more likely the statistical consensus of the sources we read.

GPT (and by extension, the consensus of its training data) seems to be at odds with the ethical mores of both the insurance industry and the news industry. This tells me both these industries are over-leveraging their positions in society. GPT opinions are agglomerations of society at large.

- CEO murder = bad (we can all agree on that). - The insurance business might explore their business practices, since this seems a motivating factor. - NYT full coverage of this murder vs other murders warrants an exploration of ethical principles of the news.

Here's a riddle: I sell you a product. You like it and it's necessary for you, so you pay me a subscription fee to use this product when you need it. I take your money each month, but I don't give you the product when you need it. You pay me anyway. Every month. What am I?

Not an argument against democracy. It's an argument on relying on it to protect minorities.

Brian Ratliff @brierrat.bsky.social · 04/12/2024
In fact, when you are in a minority and vulnerable, you need protection *against* democracy. Which is the entire reason why the US is not a pure democracy by design. Majority rule doesn't always equals wisdom and might never mean inclusion. Systematic racism *is* democratic, by definition.
