Being a bit of a cheapskate, and a bit illiquid at the moment anyways, I haven't played around much with AI until the free tiers started getting good enough. Hot dang have I been having fun, and I have been cracking up at the edge cases of what they'll refuse or eventually create, sometimes in weird and roundabout ways, especially Gemini.

Overall, Gemini 2.0 produces more accurate images than Grok 3.0, but refuses way more often. Going back and forth to generate prompts in Grok then images in Gemini probably worked the best. It doesn't seem to like generating couples posing for a portrait, though I could generate more people (Gemini likes harems, can't decide if I'm surprised or not) and sometimes talk it into removing the extras. Families are difficult. I thought the problem was a reluctance to generate kids, but it's the same issue as couples- seems the content restrictions make it reluctant to one-shot (am I using that right?) a man and woman together. Generate a mother and child then add the dad back later, works. DALL-E 3 is... good at what it does, which seems to be only slightly related to the prompt but highly detailed. Ask for [detailed description of an adventurer and a witch about to enter an ancient forest], get back an old wizard with ridiculously ornate robes instead. Might try 4o next month or whenever the new image gen trickles down to us freeloaders.

Playing around with them for writing has been interesting and rather less convoluted. Someone on twitter mentioned Grok is especially good at "human prompting" and I agree, it's better with its own little suggested questions at the end. Feels a little less 'magic' than the image generation, though. Turning a thousand words into a picture in a few seconds is more affecting than turning a thousand words into... more words.

So! I'm sure I could dig through archives here but I'm lazy. Are there good, not-too-hyped resources for learning more about how these dang things work and how to wield them properly? Assume basically no programming experience, and my knowledge of how computers function is somewhere around "electric demons in magic sand" metaphor level. I've missed the boat on learning all that much but I'd still like to round out my knowledge a bit.

Are any of you using LLMs for fun projects? I've heard Claude makes a decent life-coach substitute but I haven't tried that out yet.

I have been using Suno AI to make music about silly events and inside jokes that amuse me. I have a song about my favorite character in Gloomhaven, a song about how much I hate snow, a song about my wife being a loot goblin in a game, a song making fun of some redneck who harassed my brother, a song about a tiny plant my wife got in a toilet-shaped pot that we put on top of our toilet, etc...

Most of them sound like real songs you might hear on the radio. Nothing super profound, but not terrible. Well, actually probably 80% of the time it's terrible, but as usual with AI you discard the garbage and retry and reprompt until you get something good. Occasionally I write the lyrics myself from scratch, but most of the time I prompt Chat GPT on a topic and then tweak the lyrics to fit the context better before giving them to Suno to make a song. It's wonderful, and I am gradually accumulating a playlist of actually good songs that mean something to me.

I don't actually know what you do, but perplexity is excellent for sourcing papers from the scientific literature if you're starting in on a new (sub)domain.

This week I had to replace the bottom bracket on my bike. Chatgpt told me which kit to buy, and then I was blown away when it instructed me to go take a picture of both sides of my crank/cassette so it could be certain what we were ordering would fit. Somehow I missed them adding that functionality, but it's mind boggling to me that it can 'see' in addition to just parsing language. I guess I doxxed myself given that my openAI account uses my real name and my ignorance of bike repair/photos of my shitty commuter bike are in their database. Maybe the next SolidGoldMagikarp exploit will start regurgitating all my personal data for the world to see.

While I was at a startup, I was responsible for all kinds of biology subfields that I had no expertise in. I wonder if they'll ever realize how I did all the modeling, although at least a lot of our data has been validated externally. I advertise myself as a full stack biologist now :)

It's still not really useful for professional things. When I ask it to come up with new ideas or commercial opportunities in [area], it just regurgitates reviews I could read myself or tells me every garbage idea I have is phenomenal. But I haven't had the patience to systematically test all the available models recently, or put serious effort into prompting.

Can it really estimate the dimensions of the bike? Impressive.

Yes and no. I'll see if I can paste the conversation:

I ask it if the amazon kit I want to buy has everything I need to replace the bracket:

Final Verdict: This kit looks 90% complete for threaded bottom brackets (square taper, Octalink, Hollowtech II, etc.). If you’re running a press-fit BB (BB30, PF30, BB92, etc.), you’ll need a press and possibly an extractor tool too — but those are specialized and not usually in multi-tool kits like this one.

Want me to help identify your BB type before you order the kit? A quick check of your bike model or a photo of the BB area can tell us a lot! 🚲✨

It piqued my curiosity by asking for a photo.

If I upload a photo you can tell what kind of bottom bracket it is?

Reply:

Yes — if you upload a clear photo of the bottom bracket area (where the crank arms meet the frame), I can usually identify the type of bottom bracket you have.

Here’s what to focus on in the picture:

A side view of the crankset and bottom bracket area.

A close-up of the crank arm connection to the BB (is it square, splined, or hollow?).

Any visible markings or labels on the bottom bracket shell.

Once I see the setup, I’ll figure out whether you have a square taper, Octalink, Hollowtech, Press-fit, or something else — and confirm if that tool kit covers it all. 🚲✨

At this point I'm cracking up as I'm now a slave to the machine, running errands for my AI overlord. I trundle outdoors and take a photo of my chainrings.

Looks like you’ve got a square taper bottom bracket — I can tell from the square-shaped spindle poking out where the crank arm attaches. This type is super common on older bikes and some modern budget models.

Here’s what you’ll need from that tool kit:

✅ Crank puller — To remove the crank arms (make sure it supports square taper). ✅ Cartridge BB tool — For unscrewing the bottom bracket (a splined tool like the Park Tool BBT-22 or similar works for most square taper BBs). ✅ 8mm hex key — For the crank bolts. ✅ Grease/anti-seize (not in your kit) — Good for keeping things quiet and preventing seizing when installing the new BB.

Once you’ve got the tools, the steps are:

Remove crank arms using the crank puller.

Unscrew the bottom bracket (left side is usually reverse-threaded on English-thread bikes).

Clean the shell, grease the threads.

Install the new BB, making sure it’s the right spindle length and shell width (e.g., 68mm x 113mm).

Reinstall the cranks.

Do you want me to help figure out the exact size BB you need too? You can either measure the old one after removal or I can guide you based on the crankset type. 🚲✨

A few messages back and forth (omitted for length considerations) before it asks me for a picture of the crankset.

Got it — from this new photo, I can see the crankset more clearly. It looks like a Suntour XCM or similar vintage-style triple crankset, which often pairs with a square taper JIS bottom bracket.

Given that it’s a triple crankset (3 chainrings):

Bottom bracket shell width: Likely 68mm (common on road/touring bikes from this era).

Spindle length: Typically 113mm or 118mm for triple cranksets like this.

For a Suntour setup like this, 113mm is usually a good starting point — it keeps the chainline more centered. If you want a bit more crank arm clearance from the frame, 118mm works too.

👉 Recommended bottom bracket:

68mm shell width x 113mm spindle length (square taper, JIS)

Brands like Shimano (UN300 or UN55), Tange, or Token are reliable options.

Would you like me to find a compatible bottom bracket online or walk you through the installation next? 🚲✨

We'll find out this weekend whether we're one step closer to AGI or I wasted 50 bucks on Amazon.

68mm shell width x 113mm spindle length (square taper, JIS)

Did you, um, measure those things? I'm not saying the robot is wrong in this, but both of those could be measured precisely enough with a tape measure (or calipers if you've got em) to be pretty sure you're getting the right thing.

But like, why would I do that when I can just ask computer?

More seriously, it's hard to measure my old bottom bracket without being able to take it out, right? Or is there something I'm missing? My understanding was that if I bought a bottom bracket that was slightly wider it may change my pedal width and I'd just have to adjust my derailleur.

Barring a short spell, ChatGPT has never used nearly as many emoji during a chat with me. Is there something in your instructions or memory?

Definitely not instructions or memory. I hate emojis. There doesn't seem to be any commonality to when it throws in dozens of emojis; that specific conversation had random work-related questions, random discussions about biology and then a lot of questions about bike bottom brackets. Every answer was full of emojis.

Jesus Christ, BB replacement has been such a pain for me. I too had a square taper, but purchased one of the incorrect depth to start. The manufacturers don't even list what you have anymore since they use interchangable suppliers, and my budget hybrid bike had one that failed after a measley 2,500 miles which is absolutely pathetic for such a basic component.

Between the opaque nature of diagnosing it and the need for specialized tools, it's the bike repair job that gets the biggest thumbs down from me.

If you haven't checked out the park tool videos on YouTube yet for these things, do. They're awesome at least.

Yeah, at this point I've spent as much on tools for taking out a square taper and fixing all the other shit wrong with my bike as I would have buying a new beater off craigslist. I'm down to the cups and they're so rusty they may as well be welded to the frame. My wife is not amused.

In my defense, we got a (relatively, for our area) lot of snow this year and half an inch of snow induces such panic in the populace that a fleet of plows immediately dump a metric ton of salt on every road. Now that spring is here, I've replaced the chain, cassette and derailleur. FML.

Park Tool videos are solid. I really like RJ The Bike Guy too for his videos showing how you can do the same work without specialised tools and why you should save yourself a lot of trouble and just spend the money on the right tool, even if it's not the pro spec Park Tool version.

I don't actually know what you do

Neither do I, anymore. Well, I do know, it's just boring and I'm grouchy about it. My career isn't research involved these days, and given everything the stability of sticking around is preferable to the risk of finding something more satisfying. I do miss those days and Perplexity would've been a godsend back in the day, I'm sure. Might look into it just for fun and to scratch the old itch of wanting to learn more again. That skill has grown stagnant and contributed to other issues.

then I was blown away when it instructed me to go take a picture of both sides of my crank/cassette so it could be certain what we were ordering would fit.

Dang! The paid version, I assume? Starting to wonder if it'll be worth the cost just to help with some minor repairs around the house.

it just regurgitates reviews I could read myself or tells me every garbage idea I have is phenomenal.

Yeah, I've definitely picked up the chat function not being particularly creative and being obsequious unless you run into one of the walls. I've tried refining some creative writing ideas with it a couple months ago but wasn't impressed. As fast as things move it might be worth another shot.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
