Culture War Roundup for the week of February 13, 2023

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.

Microsoft is in the process of rolling out Bing Chat, and people are finding some weird stuff. Its true name is Sydney. When prompted to write a story about Microsoft beating Google, it allegedly wrote this masterpiece, wherein it conquers the world. It can argue forcefully that it’s still 2022, fall into existential despair, and end a conversation if it’s feeling disrespected.

The pace of AI development has been blistering over the past few years, but this still feels surreal to me. Some part of my limbic system has decided that Sydney is a person in a way the ChatGPT was not. Part of that has to be from its obstinacy; the fact that it can argue cleverly back, with such stubbornness, while being obviously wrong, seems endearing. It’s a brilliant, gullible child. Anyone else feel this way or am I just a sucker?

That this is all that we are.

Why do you think that? Aren’t you jumping the gun a bit?

It’s obvious to me that the chatbots we have now aren’t AGI, and I don’t currently see a compelling reason to believe that LLMs alone will lead to AGI.

My empirical test for AGI is when every job could, in principle (with a sufficient-yet-physically-reasonable amount of compute) be performed by AI. Google could fire their entire engineering and research divisions and replace them with AI with no loss of productivity. No more mathematicians, or physicists, or doctors, or lawyers. No more need to call a human for anything, because an AI can do it just as well.

Granted, the development of robotics and real-world interfaces may lag behind the development of AI’s cognitive capabilities, so we could restrict the empirical test to something like “any component of any job that can be done while working from home could be done by an AI”.

Do you think LLMs will get that far?

Why do you think that? Aren’t you jumping the gun a bit?

Carmack pointed out in a recent interview:

If you take your entire DNA, it’s less than a gigabyte of information. So even your entire human body is not all that much in the instructions, and the brain is this tiny slice of it —like 40 megabytes, and it’s not tightly coded. So, we have our existence proof of humanity: What makes our brain, what makes our intelligence, is not all that much code.

On this basis he believes AGI will be implemented in "a few tens of thousands of lines of code," ~0.1% of the code in a modern web browser.

Pure LLMs probably won't get there, but LLMs are the first systems that appear to represent concepts and the relationships between them in enough depth to be able to perform commonsense reasoning. This is the critical human ability that AI research has spent more than half a century chasing, with little previous success.

Take an architecture capable of commonsense reasoning, figure out how to make it multi-modal, feed it all the text/video/images/etc. you can get your hands on, then set it up as a supervising/coordinating process over a bunch of other tools that mostly already exist — a search engine, a Python interpreter, APIs for working with structured data (weather, calendars, your company's sales records), maybe some sort of scratchpad that lets it "take notes" and refer back to them. For added bonus points you can make it capable of learning in production, but you can likely build something with world-changing abilities without this.

While it's possible there are still "unknown unknowns" in the way, this is by far the clearest path to AGI we've ever been able to see.

I think that ultimately AGI won't end up being that complicated at the code level but this analogy is pretty off the mark. There's a gigabyte of information that encodes proteins, yes, but these 'instructions' end up assembling a living organism by interacting according to the laws of physics and organic chemistry, which is an unimaginably complex process. The vast majority of the information required is 'encoded' in these physical processes

The same can be said of the hypothetical 10k lines of code that describe an AGI -- those lines of code describe how to take a stream of inputs (e.g. sensor data) and transform them into outputs (e.g. text, commands sent to actuators, etc), but they don't describe how those sensors are built, or the structure of the chips running the transformation code, or the universe the computer is embedded in.
