==Explanation==
A common theme of [[xkcd]] is that one never feels that one has "transitioned to adulthood," in the sense of actually attaining the seriousness and sense of responsibility that children imagine all adults to possess. Here, the author illustrates this by imagining [[Cueball]] and [[Megan]] taking on the ultimate "adult responsibility" — having a child, treating it as they would any other engineering project. Disassembling a project to check the parts is an activity that is appropriate for a self-built computer or robot, but most people would think that disassembling a child would be impractical. Also, unless they've taken Dr. Frankenstein's course on reassembling and reanimating human beings, this would result in a grisly end for the baby{{Citation needed}}. Megan also shows her lack of child experience by holding the baby upside-down by the foot, which isn't a good idea. Her behavior could also indicate that Megan is treating the child as an object rather than a human being.

The title text implies that [[Randall]] will have kids someday. It will be surprising if they read this comic, not just because it will give them an unflattering look into their father's attitudes on having children, but because he plans to lock them in the cellar where there will be no internet access. This is possibly a reference to {{w|Kaspar Hauser}}, who, as a boy, claimed to have grown up in a dark cell in Germany in the 19th century, or to the incestuous children of {{w|Josef Fritzl}}.

This is also the topic of [[674: Natural Parenting]] and [[1384: Krypton]].

Much later, a comic with the singular version of this title was released: [[1650: Baby]]. Here, Cueball refrains from saying something as stupid as he does here about another couple's baby. The couple looks similar to the one in this comic, though that may just be due to the basic-looking art style of xkcd.

==Transcript==
:It doesn't seem right that we're old enough to have kids.
:[Megan holds a baby upside-down by one leg.]
:Megan: Sweet! We made a baby!
:Cueball: Are we sure we did it right?
:Cueball: We should disassemble it, check all the parts, and put it back together.

==Explanation==
{{incomplete|Created by a GLIDER. Needs more in-depth explanation of how the Game Evolves. Include remaining stills from the GIF in the table below. Should also expand more on why Conway is a person of note. Do NOT delete this tag too soon.}}

{{w|John Horton Conway|John Conway}}, an English mathematician, passed away of {{w|COVID-19}} on April 11, 2020. Two days later, [[Randall]] created this [[:Category:Tribute|memorial comic]]. It is the 6th memorial comic, but it is the first released in almost 5 years, since [[1560: Bubblegum]].

One of Conway's most famous creations was the {{w|cellular automaton}} known as {{w|Conway's Game of Life}}. A cellular automaton is a machine composed of cells, each of which can be in a different state. Every generation, each cell in the automaton may transition to a new state depending on a set of rules. (Conway's work in mathematics was vast and various, but he is perhaps best known in the field for discovering the {{w|surreal numbers}}, which inspired Donald Knuth to write a novel which may have been referenced back in [[505: A Bunch of Rocks]].)

Conway's Game of Life is a 2-state automaton (i.e., every cell can be "alive" or "dead") that is implemented on a two-dimensional grid of cells using the {{w|Moore neighborhood}} - this means that each cell can only be influenced by the eight cells directly surrounding it, both orthogonally and diagonally. The transition rules that Conway discovered are as follows:

* If an "alive" cell has no live neighbors, or only one live neighbor, it becomes "dead". (This simulates death by isolation).
* If an "alive" cell has four or more live neighbors, it becomes "dead". (This simulates death by overcrowding).
* If a "dead" cell has exactly three live neighbors, it becomes "alive". (This simulates birth).

Despite the simplicity of these three rules, Conway showed that patterns of amazing complexity can nonetheless develop out of simple cell arrangements. Some patterns do not evolve at all ("still lifes"), some enter a cyclic, repeating state ("oscillators"), and some reproduce their own pattern displaced by an offset, resulting in patterns that can move across the grid under their own power ("gliders" and "spaceships"). This last category is of particular interest, as it allows the Game of Life to transmit information from one location to another, allowing for rich, dynamic behavior and even for the creation of computational machines within the automaton itself.

This comic begins with the shape of a stick figure as the starting cell configuration of the Game of Life. The black cells are "alive" and the white cells are "dead". This configuration then evolves via Conway's rules, disintegrating into nothingness except for a five-cell pattern known as a "glider", which ascends up and to the right. This visually suggests a "soul" breaking away from the disintegrating corporeal body. The glider is perhaps the most iconic pattern of the Game of Life, and is often used symbolically to represent the phenomenon of emergence.

The initial state presented in the comic does actually evolve in that manner, as can be verified by entering the pattern into a cellular automaton simulator such as [http://golly.sourceforge.net/ Golly] or web services such as [https://bitstorm.org/gameoflife/ this one].

The title text simply states Conway's birth and death year: 1937-2020.

==Transcript==
:[A pixelated image of a stick figure using 21 pixels, could be a pixel Cueball, which waves with one hand up while holding the other hand down. The head consist of 7 pixels, the top row of three having two pixels beneath the two outer pixels, thus having two empty pixels beneath the central pixel. The neck and torso is a typical cross made from six pixels. The two legs are two pixels each shifted left and right of the cross. The arm to the left that waves is two pixels one down and the next back up to the level of the cross central beam. The arm to the right has the first pixel similarly but the second pixel continues one further step down. After less than one second it turns out that the image is animated, with the pixels changing according to the rules of Conway's Game of Life. The figure splits into three groups, two of which dissipates in a similar way at the bottom of the panel. The other becomes a 'glider' and moves off to the top-right corner of the image and out of the frame. The animation then repeats.]

Is it possible that the highlighted words can be shuffled to reveal a hidden message? Has Randall done this before? [[Special:Contributions/141.101.99.214|141.101.99.214]] 07:53, 2 January 2014 (UTC)

The fourth quote (.."rocked and cradled by electricity"..) seems to appear in The Champagne Standard by LANE, Annie Eichberg (Mrs. John Lane). [http://archive.org/stream/champagnestandar00lane/champagnestandar00lane_djvu.txt] {{unsigned ip|141.101.99.224}}

;Tone of the explanation

I find the tone of the explanation as it stands right now not to be in line with the rest of the explanations available on the site. For example:

By the twenty-first century I believe we shall all be telepaths.
Absurd

The plain "absurd" does not provide an explanation, only a judgement. It would be more useful it the explanation contained a link to a source with the quote, to provide context. Or provide a short bio for the person credited with the explanation. I understand the fascination behind arguing against or for the prediction, but that does not explain the comic. For example, you '''could''' argue that this particular prediction is in a sense accurate. Nowadays we all communicate in a way that people from a century ago would consider almost telepathic, given that "telepathy" means "distant experience". No, we are not mind readers, but a lot of us carry a device in our pockets that allows us to experience things at a distance.

Also, I wonder why some sentences are in boldface. I tried reading only the bold text, and it is not coherent enough. I tried reading the grey text, and it isn't coherent either. I tried several other ways of reading the texts, and I cannot find any "hidden meaning".
:I believe it's just to highlight content. The grey or non-bold text is (for the most part) non-essential to the content of the quote.

--[[User:Mem|mem]] ([[User talk:Mem|talk]]) 16:10, 2 January 2014 (UTC)

It seems to me that Randall believes that bolded text is false and grey text is true.[[Special:Contributions/173.245.50.62|173.245.50.62]] 16:13, 2 January 2014 (UTC)
:This makes no sense. Most of the grey text has little content, and Abortion is still a very debated topic.
