This is the standard way to refer to an unknown person in English, anything else sounds awkward. "What does the person want", "what does he or she want", "what does this 'someone' want", none of these will sound natural to a native speaker.
It's called "singular they". It's used like: "We have a new joiner in our team! They became the talk of the town very fast". I love this feature of the English language, while a bit confusing at first, I think it works much better than "he/she" or "s/he" when talking about someone with an unspecified, unknown or unrelated gender.
ƿrong. "they" is norþmannisċ. It sċuld be he, forðat hē and hēo ƿuld'fe melded into he, and forðat Englisċ is an Indo-Europisċ tung, ƿere ƿerelie is ðe first kin.
Command blocks can only be obtained by cheating in normal gameplay, they are used to execute server commands automatically. Using them to build a computer in the game kind of defeats the purpose of the exercise, since instead of using the game's physics to build your device, you're now mostly doing scripting with minecraft commands. The author explicitly said they didn't use any in their build.
The confusion might come from the author using commands / external software to generate and assemble parts of the redstone machine. The final machine doesn’t use any command blocks as part of it’s operation, but the description is a bit ambiguous here
there were no clickbaits there at all. no command blocks were used at all. if you were so certain, why dont you download the world and try it yourself?
