Title text: I bet my future kids will read this someday. DEAR FUTURE KIDS: how did you get internet in the cellar?
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 is impractical for a child.
The title text implies the author 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.
- It doesn't seem right that we're old enough to have kids.
- 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.
