Some examples:
- Telephones — Alexander Graham Bell was initially disappointed with the apparent uselessness of his first telephone, until the Ghostbusters quote “Who you gonna call?” fell through a rift in time and he realized he needed to invent the second telephone too.
- Train stations — Congratulations! You’ve built the world’s first train station. Where do the trains go?
- LEGO(-alike) building blocks
- Gears
Also suggest more examples too!
Edit: a couple of folks over on Mastodon independently pitched "homodependent" as a term, and I think we're onto a winner there.
