In this dialogue, someone is expressing frustration over working on a redstone machine in Minecraft. They feel they’ve accumulated a lot of what they consider "useless" knowledge, describing it as merely placing redstone on blocks and struggling with a sticky piston. The speaker is concerned about whether their setup is correct and feels that the knowledge they’re gaining isn’t practical. They’re being told that they are being taken off the project, which seems to surprise and confuse them.
