37 Welcome to Less Wrong! (5th thread, March 2013)

If you've recently joined the Less Wrong community, please leave a comment here and introduce yourself. We'd love to know who you are, what you're doing, what you value, how you came to identify as a rationalist or how you found us. You can skip right to that if you like; the rest of this post consists of a few things you might find helpful. More can be found at the FAQ.

(This is the fifth incarnation of the welcome thread; once a post gets over 500 comments, it stops showing them all by default, so we make a new one. Besides, a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves.)

A few notes about the site mechanics

Less Wrong comments are threaded for easy following of multiple conversations. To respond to any comment, click the "Reply" link at the bottom of that comment's box. Within the comment box, links and formatting are achieved via Markdown syntax (you can click the "Help" link below the text box to bring up a primer).

You may have noticed that all the posts and comments on this site have buttons to vote them up or down, and all the users have "karma" scores which come from the sum of all their comments and posts. This immediate easy feedback mechanism helps keep arguments from turning into flamewars and helps make the best posts more visible; it's part of what makes discussions on Less Wrong look different from those anywhere else on the Internet.

However, it can feel really irritating to get downvoted, especially if one doesn't know why. It happens to all of us sometimes, and it's perfectly acceptable to ask for an explanation. (Sometimes it's the unwritten LW etiquette; we have different norms than other forums.) Take note when you're downvoted a lot on one topic, as it often means that several members of the community think you're missing an important point or making a mistake in reasoning— not just that they disagree with you! If you have any questions about karma or voting, please feel free to ask here.

Replies to your comments across the site, plus private messages from other users, will show up in your inbox. You can reach it via the little mail icon beneath your karma score on the upper right of most pages. When you have a new reply or message, it glows red. You can also click on any user's name to view all of their comments and posts.

It's definitely worth your time commenting on old posts; veteran users look through the recent comments thread quite often (there's a separate recent comments thread for the Discussion section, for whatever reason), and a conversation begun anywhere will pick up contributors that way. There's also a succession of open comment threads for discussion of anything remotely related to rationality.

Discussions on Less Wrong tend to end differently than in most other forums; a surprising number end when one participant changes their mind, or when multiple people clarify their views enough and reach agreement. More commonly, though, people will just stop when they've better identified their deeper disagreements, or simply "tap out" of a discussion that's stopped being productive. (Seriously, you can just write "I'm tapping out of this thread.") This is absolutely OK, and it's one good way to avoid the flamewars that plague many sites.

EXTRA FEATURES:

There's actually more than meets the eye here: look near the top of the page for the "WIKI", "DISCUSSION" and "SEQUENCES" links.

LW WIKI: This is our attempt to make searching by topic feasible, as well as to store information like common abbreviations and idioms. It's a good place to look if someone's speaking Greek to you.

LW DISCUSSION: This is a forum just like the top-level one, with two key differences: in the top-level forum, posts require the author to have 20 karma in order to publish, and any upvotes or downvotes on the post are multiplied by 10. Thus there's a lot more informal dialogue in the Discussion section, including some of the more fun conversations here.

SEQUENCES: A huge corpus of material mostly written by Eliezer Yudkowsky in his days of blogging at Overcoming Bias, before Less Wrong was started. Much of the discussion here will casually depend on or refer to ideas brought up in those posts, so reading them can really help with present discussions. Besides which, they're pretty engrossing in my opinion.

A few notes about the community

If you've come to Less Wrong to discuss a particular topic, this thread would be a great place to start the conversation. By commenting here, and checking the responses, you'll probably get a good read on what, if anything, has already been said here on that topic, what's widely understood and what you might still need to take some time explaining.

If your welcome comment starts a huge discussion, then please move to the next step and create a LW Discussion post to continue the conversation; we can fit many more welcomes onto each thread if fewer of them sprout 400+ comments. (To do this: click "Create new article" in the upper right corner next to your username, then write the article, then at the bottom take the menu "Post to" and change it from "Drafts" to "Less Wrong Discussion". Then click "Submit". When you edit a published post, clicking "Save and continue" does correctly update the post.)

If you want to write a post about a LW-relevant topic, awesome! I highly recommend you submit your first post to Less Wrong Discussion; don't worry, you can later promote it from there to the main page if it's well-received. (It's much better to get some feedback before every vote counts for 10 karma- honestly, you don't know what you don't know about the community norms here.)

If you'd like to connect with other LWers in real life, we have meetups in various parts of the world. Check the wiki page for places with regular meetups, or the upcoming (irregular) meetups page. There's also a Facebook group. If you have your own blog or other online presence, please feel free to link it.

If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.

A list of some posts that are pretty awesome

I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:

More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.

Welcome to Less Wrong, and we look forward to hearing from you throughout the site!

Note from orthonormal: MBlume and other contributors wrote the original version of this welcome post, and I've edited it a fair bit. If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post. Finally, once this gets past 500 comments, anyone is welcome to copy and edit this intro to start the next welcome thread.

So uploads are typically not mortal, hungry for food, etc. You are asking if we create such exact simulations of humans that they will have all the typical limitations would they have the same wants as real humans, probably yes. The original question Wei Dai was asking me was about my statement that if we becomes uploads "At that point you already lost humanity by definition". Allow me to propose a simple thought experiment. We make simulated version of all humans and put them in cyberspace. At that point we proceed to kill all people. Does the fact that somewhere in the cyberspace there is still a piece of source code which wants the same things as I do makes a difference in this scenario? I still feel like humanity gets destroyed in this scenario, but you are free to disagree with my interpretation.

We make simulated version of all humans and put them in cyberspace. At that point we proceed to kill all people.

At the very lesat, by this point we've killed a lot of people. the fact that they've been backed up doesn't make the murder less henious.

Whether or not 'humanity' gets destroyed in this scenario depends on the definition that you aply to the word 'humanity'. If you mean the flesh and blood, the meat and bone, then yes, it gets destroyed. If you mean values and opinions, thoughts and dreams, then some of them are destroyed but not all of them -...

I'm also asking, should we care? More generally, I'm asking what is it about real humans we should prefer to preserve, given the choice? What should we be willing to discard, given a reason? [...] Fair enough. I've already agreed that this is true for the definitions you've chosen, so if that's really all you're talking about, then I guess there's nothing more to say. As I said before, I don't think those are useful definitions, and I don't use them myself. [...] Source code? Maybe not; it depends on whether that code is ever compiled. Object code? Yes, it makes a huge difference. [...] Some things get destroyed. Other things survive. Ultimately, the question in this scenario is how much do I value what we've lost, and how much do I value what we've gained? My answer depends on the specifics of the simulation, and is based on what I value about humanity. The thing is, I could ask precisely the same question about aging from 18 to 80. Some things are lost, other things are not. Does my 18-year-old self get destroyed in the process, or does it just transform into an 80-year-old? My answer depends on the specifics of the aging, and is based on what I value about my 18-year-old self. We face these questions every day; they aren't some weird science-fiction consideration. And for the most part, we accept that as long as certain key attributes are preserved, we continue to exist.

Well, if nothing else happens our new computer substrate will stop working. But if we remove that problem - in what sense has this not already happened? If you like, we can assume that Eliezer is wrong about that. In which case, I'll have to ask what you think is actually true, whether a smarter version of Aristotle could tell the difference by sitting in a dark room thinking about consciousness, and whether or not we should expect this to matter.
