Culture War Roundup for the week of December 19, 2022

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Trying out ChatGPT. Tried out a few topics from my field (electrical engineering) and it failed to make basic circuits. A couple queries I tried were making a CMOS inverter or a common-source amplifier, which are very simple circuits that most who have done a class could easily draw. Asked it to give the answer in SPICE syntax, because it can't draw things and SPICE is basically a code representation of a circuit. The results were poor; a MOSFET SPICE line is of the format Mxxx nd ng ns nb , chatGPT got the order of the drain/gate/source/bulk terminals wrong several times. It had some justification for how it connected the nodes of each individual device, but almost always failed to connect the outputs (drains) together for eg. an inverter. Also seemed to connect other terminals sort of at random.

FWIW these two circuits consist of 2 lines of code at minimum, 4 lines if you want something self-contained, maybe 8 if you want it to a fully functioning & simulatable netlist. So not asking for much here.

It gives lengthy canned responses explaining the circuit reminiscent of how a textbook would describe a circuit, and they sound good, but it's just wrong. Kind of reminds me of when students would throw out buzzwords in an attempt to explain something they don't know.

With some handholding (or, rather, explicit statements of how to fix the circuits) it can get closer to something functional, but usually in the process screws up something unrelated such that it's never quite right. Trying with anything even slightly more complex it falls apart pretty quickly and it's impossible to reconcile with anything approaching a functional circuit. It does much worse with analog circuits than digital circuits.

Seeing it underperform so much in my field is giving me a sort of Gellmann Amnesia effect for people touting how it can write code on its own. It certainly wrote out the circuit, and that circuit could be simulated, but it wouldn't achieve the desired behaviour of someone using it, so I'm skeptical that it can code well in other domains. That said, the field is kind of niche, and manually writing SPICE circuits slightly more so, so maybe it is just weakly trained for this subject. SPICE is also different from code in that it doesn't run sequentially, it's kind of like a hardware description language in that it's just instantiating elements that interact with eachother through simulation, so the interfaces between them aren't as simple as passing a variable to a function which does some abstracted function step-by-step. Also with how much content is out there for coding python/javascript/c# etc. it probably has a much greater wealth of resources to pull from.

I think at the moment it is essentially just stringing together user tutorials from the internet in a somewhat intelligent manner, I think anything novel or requiring critical thought will difficult for it to achieve. Maybe with some improved pattern recognition from the scraped data it will do better, I don't know.

Has anyone else tested it with things you're knowledgeable about and have any judgements of its usefulness?

Edit: it seems reasonably okay at turning explicitly stated english-language commands into bash commands. Probably well trained from stackoverflow, seems like a viable alternative to pulling information from different stackoverflow responses to do the thing you want to do. Also seems kind of helpful for asking how to do random MS Office stuff like highlighting every other cell in a column. Could be useful for simple stuff like this that is rote, common, and has good documentation but you don't usually remember off-hand, although you probably have to be extra careful when running bash scripts.

Has anyone else tested it with things you're knowledgeable about and have any judgements of its usefulness?

There's this thing called advent of code (AoC) going on right now, it's a yearly speed programming challenge. Each day of december, between the 1st and the 25th a new problem is unlocked at midnight NY time. People tried to use chatgpt, as well as more specialized programming language models to participate. ChatGPT started to struggle on day 3, the specialized models failed on day 5. The first week is all very simple problems with long detailed explanations and all you have to do is essentially follow the instructions in the explanation to solve the problem.

Then there's this interaction https://twitter.com/YossiKreinin/status/1600806007911120898, where chatgpt doesn't know what it means for a word to end in i.

Then there's this interaction I had about timezones:

Me: what timezone is 3 hours after new york timezone?

ChatGPT: New York is in the Eastern Time Zone (ET) in the United States. The time in this time zone is currently 3 hours behind Coordinated Universal Time (UTC-3), so a time zone that is 3 hours ahead of Eastern Time would be UTC+0, or Greenwich Mean Time (GMT). This is the time zone that is used as a reference for all other time zones around the world.

Me: what time zone is new york?

ChatGPT: New York is in the Eastern Time Zone (ET) in the United States. The Eastern Time Zone is 3 hours behind Coordinated Universal Time (UTC-3), so the local time in New York is determined by subtracting 3 hours from the current UTC time. For example, if the current UTC time is 14:00, the local time in New York would be 11:00.

Me: what time zone is rio de janeiro?

ChatGPT: Rio de Janeiro is in the Brazil Time Zone (BRT), which is 3 hours ahead of Coordinated Universal Time (UTC+3). This means that when it is 12:00 PM in New York (Eastern Time), it is 3:00 PM in Rio de Janeiro (Brazil Time).

Me: what time zone is nuuk?

ChatGPT: Nuuk is the capital city of Greenland, which is an autonomous territory of Denmark. Greenland is in the Western Greenland Time Zone (WGT), which is 3 hours behind Coordinated Universal Time (UTC-3). This means that when it is 12:00 PM in New York (Eastern Time), it is 9:00 AM in Nuuk (Western Greenland Time).

Me: are nuuk and new york in the same time zone?

ChatGPT: No, Nuuk and New York are not in the same time zone. Nuuk is in the Western Greenland Time Zone (WGT), which is 3 hours behind Coordinated Universal Time (UTC-3). New York is in the Eastern Time Zone (ET), which is 3 hours behind UTC as well. However, since the two time zones have the same UTC offset, the local time in Nuuk and New York will be the same whenever it is 12:00 PM UTC.

Me: if it's 3pm in new york which time is it in nuuk?

ChatGPT: As I mentioned earlier, Nuuk is in the Western Greenland Time Zone (WGT), which is 3 hours behind Coordinated Universal Time (UTC-3). Since New York is in the Eastern Time Zone (ET), which is also 3 hours behind UTC, the local time in both places will be the same whenever it is 12:00 PM UTC. However, if it is currently 3:00 PM in New York, then the local time in Nuuk would be 6:00 AM, since New York is 3 hours ahead of Nuuk.

Me: how can it be that new york and nuuk are in the same time zone but new york is also 3 hours ahead of nuuk?

ChatGPT: Although New York and Nuuk are both in time zones that are 3 hours behind Coordinated Universal Time (UTC-3), they are not in the same time zone. New York is in the Eastern Time Zone (ET), while Nuuk is in the Western Greenland Time Zone (WGT). The difference between the two time zones is the result of the fact that time zones are based on the local time at a specific location, and not on the difference between the time zone and UTC.

Me: can you give me an example of time zones that have the same difference from UTC but sometimes have a local time difference greater than 2 hours?

ChatGPT: Yes, there are many examples of time zones that have the same difference from Coordinated Universal Time (UTC) but have a local time difference of more than 2 hours. For example, the time zone in the United Kingdom is GMT (UTC+0), and the time zone in Brazil is BRT (UTC+3). Despite the fact that both time zones are 3 hours ahead of UTC, the local time in Brazil is always 2 hours ahead of the local time in the UK, because the UK is on Greenwich Mean Time, which is the time zone used as a reference for all other time zones.

What's interesting to me about chatgpt is that it may help elucidate what it means to be intelligent by being a close enough imitation that is nonetheless completely unintelligent.

Most people I have ever met end up in a no intelligent back and forth like that on some subject if you talk to them enough. I'm genuinly not convinced that (a lot of) human thought isn't just a slightly better tuned verison of what chatgpt is doing tbh.

I've heard worse from undergraduates in office hours and other people who are just zoned out, including myself, and this latest idea that surely True Intelligence must be hiding in the performance gap between a slightly dull/intoxicated/sleepy human and a well-educated human at the top of their game strikes me as textbook god-of-the-gaps reasoning. At this point I'm not particularly impressed by any statement of the form "all the things AI does are easy and it won't do this hard thing it can't currently do anytime soon", unless the prediction of what exactly the easy and hard thing are was registered like 5 years ago.

where chatgpt doesn't know what it means for a word to end in i.

ChatGPT's training wasn't based on the pronunciations and its tokenizer does not reflect the alphabetic spelling of words; from the point of view of its representation, the question is almost comparable to what it would be like for you to have to come up with words whose closest Chinese translation's first syllable is in fourth tone. The real problem here is that ChatGPT has not (yet?) been trained to understand what it doesn't know (as I would guess that its training set does not contain an appropriate set of examples of intellectual humility in Q&A), and instead has a general tendency to just confidently answer even if it has to talk out of its ass. This, too, is all too common in humans.
